Not necessarily Lung cancer surgery only removes the entire lung, a procedure called pneumonectomy, in specific situations, usually when a tumour is large or sits too centrally to spare surrounding lung tissue. Most operations aim to remove as little healthy lung as possible while still clearing the cancer completely.

According to Dr. Sandeep Nayak, surgical oncologist in Bangalore with over 24 years of experience treating solid tumors, “Patients hear lung cancer surgery and assume they’re losing the whole lung, and that fear alone stops some of them from even pursuing surgery. That’s genuinely not the usual outcome. Most cases only need a lobe removed, sometimes even less, and a well-planned operation protects as much breathing capacity as the cancer allows.”

If lung cancer surgery is already on the table for your case, our Lung Cancer treatment page covers how the extent of surgery actually gets decided.

• Tumour size and location matter most, a small tumour tucked in one segment allows far more lung to be preserved than one sitting near major airways.
• Lung function testing beforehand checks whether a patient can safely tolerate losing more tissue, this genuinely shapes what’s offered as an option.
• Lymph node involvement and how the cancer has spread locally also factor into how much surrounding tissue needs to come out.
• Minimally invasive approaches like VATS don’t change how much lung gets removed, but they do reduce the trauma of getting there.

We’ve written more about how this minimally invasive approach actually works in What Is VATS Surgery for Lung Cancer?, worth reading if the surgical approach itself is what’s on your mind.

Lynch syndrome is a fairly common inherited genetic condition, and it significantly raises a person’s lifetime risk of certain cancers, particularly colorectal and endometrial, or uterine, cancer. It’s caused by a fault in one of a small group of genes responsible for repairing DNA mistakes as cells divide, when that repair process doesn’t work properly, errors build up over time and can eventually lead to cancer.

According to Dr. Sandeep Nayak, surgical oncologist in Bangalore with over 24 years of experience treating solid tumors, “Lynch syndrome gets missed more often than it should, mainly because families don’t always connect the dots across generations. One relative with colon cancer in their 40s, another with uterine cancer a decade later, these can look unrelated on the surface. But that pattern is exactly what should prompt a genetic conversation.”

If colorectal cancer is already part of your family’s history, our Colon Cancer treatment page covers screening and treatment approaches relevant to higher-risk patients specifically.

• Multiple relatives across generations diagnosed with colorectal or endometrial cancer, particularly at a younger age, is the strongest signal worth acting on.
• One isolated cancer diagnosis in a family, even a serious one, doesn’t automatically point to Lynch syndrome on its own.
• Genetic testing is usually recommended when this specific pattern shows up, not for every cancer diagnosis by default.
• A confirmed diagnosis changes screening recommendations significantly, often meaning earlier and more frequent colonoscopies for the person and at-risk relatives.

We’ve gone into how hereditary risk actually plays out across a family more broadly in Will My Children Get Cancer Because of Me?, worth reading if this question is already on your mind.

Yes, diet genuinely affects colorectal cancer risk, that part’s well established at this point. What’s less talked about is that not every dietary factor carries the same weight. Some links are backed by decades of consistent data, others are still being worked out. Understanding which is which matters more than another generic list of foods to eat or avoid.

According to Dr. Sandeep Nayak, surgical oncologist in Bangalore with over 24 years of experience treating solid tumors, “Patients want a simple answer, cut this out, eat more of that, and I understand the appeal. But the honest picture is that diet shifts risk over years, not overnight, and some factors move the needle far more than others. Knowing where the strongest evidence actually sits helps people focus their energy where it counts.”

This connects directly to something worth understanding if diet is part of a bigger family risk picture, our earlier piece on Right Age to Start Colonoscopy Screening in India? goes into why screening still matters regardless of how carefully someone eats.

• Diet shifts risk over years, not weeks, so short-term changes won’t show up as a measurable difference immediately.
• Genetics and family history can outweigh diet in some individuals, which is exactly why screening age recommendations exist separately from lifestyle advice.
• India’s rising colorectal cancer rates in younger adults line up closely with dietary shifts toward processed food and away from traditional fibre-rich meals over the past couple of decades.
• No diet, however careful, replaces the need for screening at the recommended age, it lowers risk, it doesn’t eliminate it.

HIPEC generally isn’t recommended for patients whose cancer has spread beyond the abdomen, since the whole point of the procedure is treating disease confined to the abdominal cavity. It’s also not usually suitable for patients too physically frail to withstand a long, intensive operation, HIPEC surgery can run many hours and demands real physiological reserve to recover from well.

According to Dr. Sandeep Nayak, surgical oncologist in Bangalore with over 24 years of experience treating solid tumors, “Patients sometimes come in hoping HIPEC is an option regardless of how advanced things are, and I understand that hope completely. But offering a major operation that won’t actually help isn’t kindness, it’s just added risk with no real benefit. Being honest about who isn’t a candidate is just as important as knowing who is.”

If HIPEC candidacy is genuinely on the table for your case, our HIPEC treatment page covers what the actual procedure and eligibility assessment involve.

• Imaging and, often, diagnostic laparoscopy assess how much disease is present and where, before any final decision gets made.
• PCI scoring, covered in more depth on our own site, plays a central role in judging whether complete removal is realistic.
• A tumour board reviews every case, weighing cancer type, spread, and the patient’s overall fitness together, not any single factor in isolation.
• Being ruled out for HIPEC doesn’t mean no options remain, systemic chemotherapy and other approaches still apply depending on the case.

We’ve written more about how that scoring system actually works in What Is Peritoneal Cancer Index for HIPEC?, worth reading if PCI already came up in your consultation.

Yes, H. pylori infection can increase the risk of stomach cancer. Although most infected people never develop cancer, persistent H. pylori infection can cause chronic inflammation and progressive changes in the stomach lining that may eventually contribute to cancer in some individuals. Because H. pylori is a treatable infection, testing and appropriate eradication treatment can be an important part of reducing gastric cancer risk in people who are infected. 

Prof. Dr. Sandeep Nayak, surgical oncologist in Bangalore with over 24 years of experience treating gastrointestinal cancers, puts it this way: “H. pylori doesn’t cause cancer overnight. It’s a slow burn, chronic inflammation building up in the stomach lining over years, sometimes decades, before anything turns malignant. That long runway is actually good news, because it means there’s time to catch and treat the infection before it gets that far.”

The connection isn’t immediate, and it isn’t automatic either. Most people carrying the bacteria never develop cancer. But in those who do, the path tends to follow a similar pattern over time.

• Persistent infection triggers chronic gastritis, ongoing inflammation of the stomach lining
• Long-term inflammation can lead to atrophic gastritis, where the stomach lining thins out
• Thinned, damaged tissue is more prone to abnormal cell changes over the years
• Those changes can eventually progress toward gastric adenocarcinoma, the most common type of stomach cancer

None of this happens on a fixed timeline, and factors like diet, smoking, and genetics all play a role alongside the infection itself. If cancer does develop, treatment often needs a team-based approach. Our stomach and esophageal cancer treatment program covers diagnosis, staging, and surgical management for exactly this kind of case.

This is where the answer gets a little less black and white. Guidelines generally lean toward treating the infection once it’s confirmed, but there’s nuance to it.

• Testing usually happens through a breath test, stool test, or endoscopic biopsy
• Treatment typically involves a combination of antibiotics plus an acid-reducing medication
• Eradicating the infection significantly lowers long-term stomach cancer risk, particularly if caught before atrophic changes set in
• Family history or a prior diagnosis of gastric cancer usually makes treatment more urgent rather than optional

This ties back to something we touched on in our post about clear surgical margins and why a clean result at one point doesn’t guarantee the story’s over. H. pylori works on a similar principle in reverse, catching and treating the root cause early changes what happens years down the line.
