Yes, some viruses cause cancer. They account for about 15 to 20 percent of all cancers worldwide. The WHO has classified seven viruses as oncogenic, and they include HPV, hepatitis B and C, EBV, HTLV-1, KSHV and HIV. None of them cause cancer the day they enter the body. They set up chronic infection first, then trigger cellular changes that show up as cancer 15 to 40 years later. Vaccines and timely treatment stop most of these in their tracks.

According to Prof. Dr. Sandeep Nayak, Surgical Oncologist in India, “Virus linked cancers are among the most preventable cancers in modern medicine, because we already have vaccines or effective treatments for the major ones. The challenge is awareness, most patients don’t realise that HPV vaccination or hepatitis B screening today protects them from cervical or liver cancer decades later.”

Seven viruses make the WHO carcinogenic list. Each one works a different way.

• HPV virus: Human papillomavirus causes most cervical cancers. It’s also behind anal, throat, mouth and penile cancers. HPV vaccines prevent over 90 percent of these.
• Hepatitis B and C: Both viruses cause long term liver inflammation. Over years, that inflammation pushes the liver toward cancer. HBV has a vaccine. HCV now has cure level treatment.
• EBV virus: Epstein Barr virus is linked to nasopharyngeal cancer, certain lymphomas and a small share of stomach cancers. Almost everyone carries EBV. Cancer is the rare exception, not the rule.
• HTLV and KSHV: HTLV-1 leads to a specific adult T cell leukaemia. KSHV is behind Kaposi sarcoma. Both are rare in India but matter where they occur.

For patients diagnosed with virus linked cancers, robotic cancer surgery brings precise removal of tumours like cervical, liver, throat and head and neck cancers.

Prevention is genuinely possible for most of these. The tools already exist.

• HPV vaccine: Vaccination between ages 9 and 26 prevents cervical and oropharyngeal cancers decades later. Available for boys and girls. Three doses or two, depending on age.
• Hep B vaccine: Hepatitis B vaccination is part of routine childhood immunisation in India. It directly prevents one of the biggest causes of liver cancer worldwide.
• Hep C treatment: Modern antivirals cure over 95 percent of HCV patients in 8 to 12 weeks. Catch it early and liver cancer never happens.
• Safe practices: Safe sex, no shared needles, screened blood transfusions, routine virus checks. All of these cut exposure to oncogenic viruses meaningfully.

For patients curious about how virus links and cancer transmission sometimes get confused, our blog on whether cancer is a communicable disease clears up the misconception.

A cyst is a fluid filled sac that’s almost always benign and rarely turns cancerous. Cancer, on the other hand, is a solid mass of abnormal cells with the potential to invade surrounding tissue and spread elsewhere in the body. Most cysts stay stable, cause no real trouble and need only watching, while cancer needs active treatment because of its behaviour. Imaging and biopsy are the tools that confirm which is which.

According to Prof. Dr. Sandeep Nayak, Surgical Oncologist in India, “A cyst and a cancer are biologically different from the start. One is a fluid pocket the body has walled off, the other is uncontrolled solid cell growth with invasive potential. Knowing which it is decides everything from whether you watch and wait or move to surgery and beyond.”

A cyst is the body’s way of walling off something it doesn’t need.

• Fluid pocket: A cyst forms when a sac of tissue traps fluid, air, pus or other material. It’s a contained collection, not a growing mass of new cells.
• Mostly harmless: Most cysts cause no real symptoms beyond a visible lump or mild pressure. They sit in place for years without any malignant behaviour.
• Common types: Sebaceous cysts on the skin, ovarian functional cysts, breast cysts, kidney cysts, ganglion cysts on joints, all are routinely benign and very common.
• Watch usually: Most simple cysts get watched on ultrasound or scan over time. Surgery is needed only when they grow large, painful or look complex.

For cysts that do need surgical removal, especially when complex features raise malignant concern, robotic cancer surgery brings precise organ sparing dissection in delicate areas.

Side by side, the two are biologically distinct. Here’s the comparison.

• Imaging clue: A simple cyst looks uniform and smooth on ultrasound. Cancer typically shows irregular borders, solid parts, blood flow on Doppler imaging.
• Growth pattern: Cysts stay roughly the same size or shrink, sometimes fluctuating with hormones. Cancers grow over weeks or months in a consistent direction.
• Other symptoms: Cysts almost never cause weight loss, fatigue, fever or systemic signs. Cancer often comes with these alongside the lump.
• Biopsy decides: When imaging is unclear or features are concerning, a tissue biopsy gives the definitive answer that no scan alone can match.

For patients dealing specifically with a painless lump and wondering whether it’s a cyst or something more, our blog on painless lump and cancer walks through the warning patterns.

Dr. Sandeep Nayak has spent 24 years in surgical oncology. He holds DNB qualifications in Surgical Oncology and General Surgery and trained further with a fellowship in Laparoscopic and Robotic Onco Surgery. He never reassures a cyst as benign without proper imaging and clinical evaluation, because the small fraction of cysts that aren’t harmless look almost identical to the ones that are on basic scans.

That careful evaluation is what separates true reassurance from false reassurance for patients with lumps and cysts. Every case at MACS Clinic goes through tumour board review, where the diagnostic plan is set together. Call +91 8104310753 to book your consultation.

The thyroid is a small, butterfly-shaped gland in the neck, yet it controls metabolism, energy, and the hormones that govern reproduction. As its reach is so wide, even a minor imbalance can disrupt the body’s normal rhythm. This is where thyroid health and fertility become closely linked: when hormone levels run too high or too low, ovulation, menstrual cycles, and sperm quality can all suffer, making conception harder.

Dr. Sandeep Nayak, an ace surgical oncologist in Bangalore with deep expertise in thyroid and cancer care, explains:

Thyroid imbalance is one of the most common yet overlooked causes of infertility. He points out that many couples try for months before realizing a simple thyroid test holds the answer, and that fertility often improves once the imbalance is corrected.

Known for his work in advanced robotic and minimally invasive surgery, Dr. Sandeep Nayak guides patients through thyroid evaluation, nodule assessment, and treatment when a serious condition is suspected. This makes him a trusted name for cancer treatment in Bangalore.

First, here’s why this gland matters so much for reproduction.

The thyroid produces two key hormones, T3 and T4, that regulate how every cell in the body uses energy. These hormones also interact closely with the reproductive system. In women, they influence ovulation and the menstrual cycle. In men, they affect sperm production and quality.

When thyroid hormone levels are too high (hyperthyroidism) or too low (hypothyroidism), this delicate balance is disturbed. The result can be irregular cycles, difficulty conceiving, or a higher chance of complications during pregnancy. Healthy thyroid function, therefore, is a quiet but essential foundation for fertility in both partners.

Curious whether your thyroid could be affecting your fertility? Keep reading.

Both an underactive and an overactive thyroid can disrupt reproduction in several ways:

• Disrupted ovulation

Hypothyroidism can prevent the ovaries from releasing an egg each month, making conception unlikely.

• Irregular menstrual cycles

Thyroid imbalance often causes cycles that are too heavy, too light, or unpredictable.

• Hormonal interference

Low thyroid hormone can raise prolactin levels, which further suppresses ovulation.

• Luteal phase problems

The second half of the cycle can be shortened, and this can make it difficult for an embryo to implant.

• Male fertility effects

Thyroid imbalance may have an impact on the sperm level, motility, and libido in men.

• Higher miscarriage risk

Untreated thyroid disorders are linked to early pregnancy loss.

The encouraging news is that thyroid dysfunction-caused fertility problems are often easily correctable when diagnosed.

Now, what should actually make you suspicious?

Thyroid problems can be subtle, but certain signs are worth noting, especially alongside fertility concerns.

Possible signs of an underactive thyroid:

• Constant fatigue and low energy
• Unexplained weight gain
• Feeling cold often
• Dry skin and hair thinning
• Heavy or irregular periods
• Low mood or difficulty concentrating

Possible signs of an overactive thyroid:

• Rapid weight loss
• Racing heartbeat or palpitations
• Anxiety and restlessness
• Light or skipped periods
• Trouble sleeping
• Excessive sweating

“If several of these sound familiar, it is worth raising them with a doctor. A simple blood test can confirm whether your thyroid is the cause,” advises Dr. Sandeep Nayak, an acclaimed oncologist in Bangalore.

Conceiving is one step. Carrying a healthy pregnancy is the next step.

Thyroid hormones are vital during pregnancy, particularly in the first trimester when the baby relies entirely on the mother’s supply. Unmanaged thyroid disorders during this time can raise the risk of complications.

Untreated hypothyroidism in pregnancy has been linked to miscarriage, premature birth, low birth weight, and effects on the baby’s brain development. Untreated hyperthyroidism can lead to pre-eclampsia, preterm delivery, and other concerns. This is why doctors often check thyroid levels early in pregnancy and continue to monitor them throughout pregnancy.

The good news is that with proper treatment and regular monitoring, most women with thyroid disorders go on to have healthy pregnancies and healthy babies.

Here’s the reassuring part: most thyroid issues are highly treatable.

Treatment depends on whether the thyroid is underactive or overactive:

• Hypothyroidism is usually managed with daily thyroid hormone replacement medication. Once levels are stabilized, ovulation and cycles often return to normal.
• Hyperthyroidism may be treated with anti-thyroid medication, and in some cases, other interventions, depending on the cause.
• Regular monitoring through blood tests ensures hormone levels stay in the ideal range, especially before and during pregnancy.
• Fertility support may be combined with thyroid treatment if conception is still difficult after hormone levels are corrected.

In some cases, thyroid problems are linked to nodules or, less commonly, thyroid cancer. When a suspicious nodule is found, specialist evaluation is important. For those in Bangalore who need thyroid cancer treatment, Dr. Sandeep Nayak offers expert assessment and advanced surgical care. You can read more about thyroid disease during pregnancy from the American Thyroid Association for trusted background information.

In addition to medication, some small daily habits can support your thyroid.

• Eat a balanced diet. Add sufficient iodine, selenium, and zinc, which support thyroid function. Avoid extreme or restrictive diets.
• Manage stress. Chronic stress can disturb both thyroid and reproductive hormones. Rest, sleep, and relaxation are important.
• Stay active. Regular, moderate exercise supports metabolism and hormonal balance.
• Maintain a healthy weight. Both being underweight and being overweight can affect thyroid and fertility.
• Take medication consistently. If prescribed thyroid medication, take it exactly as advised and never stop without consulting your doctor.
• Get regular check-ups. Periodic thyroid checks are used to detect imbalances early, particularly when planning a family.

These steps are not a substitute for medical treatment, but they promote the best possible health for conception.

A tumour board is a weekly meeting. Surgical, medical and radiation oncologists, pathologists and radiologists, all sitting together, reviewing each cancer case as a team. The scans get looked at fresh. The biopsy slides get a second read. Five sets of expert eyes go over the same case before a final treatment plan reaches you. This is the quiet engine behind modern cancer care, and it’s why team based outcomes beat single doctor decisions almost every time.

According to Prof. Dr. Sandeep Nayak, Surgical Oncologist in India, “Tumour board is where the real treatment decision gets made for almost every complex cancer case. The surgical view, the chemo view, the pathology read, they all land on the same table. The plan that comes out is sharper than any single opinion, and that’s what patients deserve from modern oncology.”

The team includes every specialist your case actually needs.

• Surgical oncologist: Looks at whether the tumour can be removed, what kind of operation suits, and whether organ function or fertility can be preserved alongside.
• Medical oncologist: Weighs the chemotherapy, targeted therapy and immunotherapy options. Decides what’s needed before surgery, what’s needed after, and how to sequence the whole plan.
• Radiation oncologist: Checks if radiation belongs in the plan, when in the timeline, and how to deliver it without harming the healthy tissue around the tumour.
• Pathologist plus radiologist: Reads the biopsy slides afresh, confirms the diagnosis, reviews every scan. Their findings ground each recommendation in evidence, not assumption.

For patients whose plan involves surgery, robotic cancer surgery is one part of a complete approach the tumour board signs off on first.

The benefits aren’t theoretical. They’re evidence backed and measurable.

• Catches mistakes: Multiple expert eyes on the same biopsy and scans catch staging errors, missed details, misinterpretations. Things a single doctor might overlook simply because nobody else is double checking.
• Right sequence: The team decides what should come first. Chemo, surgery, or radiation. That call often matters as much as the treatments themselves do.
• Newer options: Tumour boards regularly bring up molecular profiling, clinical trial slots and newer targeted therapies. Things individual practitioners might not actively follow week to week.
• Confidence in plan: When five specialists agree on a plan, you and your family can move forward knowing it isn’t one person’s judgement alone behind it.

For patients still weighing whether to seek another expert view, our blog on second opinion in cancer diagnosis walks through what to ask and where to go.

Dr. Sandeep Nayak has spent 24 years in surgical oncology. He holds DNB qualifications in Surgical Oncology and General Surgery and trained further with a fellowship in Laparoscopic and Robotic Onco Surgery. Every case at MACS Clinic goes through tumour board review before any surgical or treatment plan is finalised, so patients get the full team’s input, not a single specialist’s call.

That team based approach is what separates modern oncology from the older single doctor model. Every plan gets tumour board sign off first. Surgery or chemo follows from there. Call +91 8104310753 to book your consultation.

Some cancers grow inside organs that simply have no way to raise an alarm. The pancreas, ovaries, kidneys and liver hold very few pain nerves, and there’s loose space around them, so a tumour can sit and expand for months without pressing on anything that would actually hurt. By the time mild fatigue, bloating or a vague back ache shows up, the cancer is often already past the early stage. Catching these in time means screening high risk people, not waiting for symptoms.

According to Prof. Dr. Sandeep Nayak, Surgical Oncologist in India, “Silent cancers stay silent because the organs they start in have room to grow and no pain signals to trigger. By the time symptoms appear, the disease has often crossed into late stages. This is exactly why family history matters and why high risk groups should screen rather than wait for warning signs that may never come early enough.”

The biology of where they grow gives them an unfair head start.

• No pain nerves: The pancreas, ovaries and liver carry very few pain sensors inside them. A tumour can grow there for months and nothing inside the body raises a flag.
• Plenty of space: The abdomen has loose room around organs. Tumours expand for ages before pressing on anything important enough to actually hurt.
• Vague early signs: When something does turn up, it’s mild fatigue, a bit of bloating, dull back ache. The same things a dozen everyday issues cause. Nobody links it to cancer.
• Spread feels normal: By the time symptoms appear properly, the cancer has often already moved into lymph nodes or other organs. What the patient feels is just general unwellness, not a clear warning.

For patients caught at a treatable stage, robotic cancer surgery brings precise tumour removal even in deep, tricky areas like the pancreas or pelvis.

Smart, targeted screening is the answer. Not generic worry.

• Know your risk: Family history of cancer, BRCA or Lynch syndrome, long term smoking, chronic pancreatitis, hepatitis. Any of these pushes you into a group worth screening on purpose.
• Targeted scans: Ultrasound, CT or MRI done at the right intervals catches kidney, ovarian and pancreatic tumours earlier than symptom watching ever does.
• Blood markers: Tumour markers like CA 125 for ovarian or CA 19 9 for pancreatic, paired with imaging, help spot suspicious cases in higher risk patients.
• Listen to vague signs: Bloating that doesn’t settle in two weeks. Weight dropping for no reason. New mid back pain that doesn’t fit a posture cause. Worth a specialist’s eyes, not another month of waiting.

To understand which cancer types tend to be hardest to catch and treat, our blog on the most dangerous cancers walks through why some stay hidden longest.

Dr. Sandeep Nayak has spent 24 years in surgical oncology, with DNB qualifications in Surgical Oncology and General Surgery and a fellowship in Laparoscopic and Robotic Onco Surgery. He builds screening plans for high risk patients, takes vague but persistent symptoms seriously instead of brushing them off and uses robotic precision to remove tumours in the deep, hard to reach organs where silent cancers usually start.

That kind of proactive screening plus minimally invasive surgery is what genuinely changes outcomes here. Every case at MACS Clinic goes through a full tumour board, where the treatment plan is set together. Call +91 8104310753 to book your consultation.
