The liver is the most common first stop for cancers that spread. It’s all about blood flow. Blood from the entire gut, pancreas and spleen flows directly into the liver through the portal vein, carrying any loose tumour cells with it. The liver also has a second blood supply from the hepatic artery. Two roads in, lots of cells getting trapped. Add the slow sinusoidal flow inside the liver and the rich growth environment, and you’ve got a perfect filter for cancer cells looking to settle.

According to Prof. Dr. Sandeep Nayak, Surgical Oncologist in India, “The liver becomes the first metastatic site for many cancers simply because of plumbing. Blood from the digestive system runs straight through it via the portal vein, so tumour cells from colon, pancreatic or stomach cancers land there first. It’s why we always image the liver carefully in any abdominal cancer staging.”

A few reasons stack up together. Anatomy mostly does the rest.

• Portal vein highway: All blood draining the gut, pancreas and spleen passes through the liver first. Any cancer cell that breaks off from these organs gets carried straight in.
• Dual blood supply: The liver takes blood from two sources, the portal vein and the hepatic artery. More blood flow means more chances for circulating tumour cells to lodge.
• Slow sinusoidal flow: Blood slows down inside the liver’s tiny sinusoid channels. Cancer cells have time to stick to the lining and start growing there.
• Rich growth environment: The liver’s full of growth factors, oxygen and nutrients. Tumour cells that land here find a welcoming neighbourhood.

For patients diagnosed with liver mets that can be surgically removed, robotic cancer surgery brings precise resection while sparing healthy liver tissue.

Pattern’s fairly predictable once you know the anatomy.

• Colorectal cancer: The classic liver-first cancer. Blood from the colon and rectum drains via the portal vein straight to the liver. About half of all colorectal patients develop liver mets.
• Pancreatic and stomach: Same portal vein route applies. Both drop liver mets early in the disease, often before other organs show involvement at all.
• Breast cancer: Goes to bone first usually, but liver is the third most common site. The liver becomes a sanctuary site once breast cancer cells settle there.
• Lung and ovarian: Lung cancer can hit the liver through the systemic circulation. Ovarian spreads to the peritoneum first, but the liver follows close behind.

Most cancer patients can still eat non vegetarian food during treatment, with lean fish, chicken and eggs being the main protein sources oncologists recommend. The real limits sit elsewhere, on processed meats, excess red meat and raw or undercooked items. Stopping all non veg outright? That’s a cultural habit, not an evidence based oncology rule.

According to Prof. Dr. Sandeep Nayak, Surgical Oncologist in India, “Cancer patients on treatment have higher protein needs, not lower. Cutting out non vegetarian food often makes recovery harder because plant protein alone struggles to meet what most patients need through surgery, chemo or radiation. Eggs, fish and chicken remain part of standard oncology nutrition advice unless there’s a specific medical reason to restrict them.”

Cancer pushes the body’s protein demands up. Choosing the right sources helps it cope.

• Muscle preservation: Treatment breaks muscle down faster than usual. The right amount of protein, particularly from animal sources, slows that loss and keeps the patient stronger through chemo cycles.
• Wound healing: Surgery means tissue repair. The body uses amino acids to rebuild. Eggs, fish and chicken bring the full set of amino acids in one source. Plants usually don’t.
• Immune support: Chemo lowers immunity between cycles. Lean protein helps the immune system rebuild. The body fights infection better when it’s getting what it needs.
• Energy balance: Patients on plant only diets can lose weight quickly, sometimes edging into cachexia. Animal protein packs dense calories that vegetarian sources struggle to deliver.

For patients recovering from cancer surgery, robotic cancer surgery supports faster healing, but nutrition during recovery is what carries the patient through the longer term.

The food category itself isn’t the issue. The specific items inside it are.

• Recommended: Eggs. Fresh fish. Skinless chicken. Low fat dairy. Well cooked, properly hygienic, moderate portions. These are the working foods of cancer recovery.
• Limit intake: Red meat like mutton and beef. Once or twice a week, no more. Strong evidence ties excess red meat to colorectal cancer risk.
• Avoid entirely: Processed meats. Sausages, salami, bacon, ham. WHO classifies these as Group 1 carcinogens, sitting in the same category as tobacco. Not worth the risk during cancer.
• Skip raw items: Sushi, raw eggs, soft cheeses, undercooked meat. Chemo lowers immunity, so food borne infection risk shoots up. Cook everything through.

A surgical drain is a small flexible tube placed inside the body at the end of an operation. The other end sits in a bulb outside the skin. Its job? Pull out fluid, blood and lymph that collect after surgery before it builds up under the skin. Most drains stay in for 3 to 10 days. They come out when daily output drops below 30 ml for two days running. Quick to remove. Almost always uncomfortable rather than painful.

According to Prof. Dr. Sandeep Nayak, Surgical Oncologist in India, “Drains aren’t there to make recovery harder. They prevent fluid pockets called seromas that delay healing or get infected. Once the daily output falls under 30 ml and the wound looks settled, the drain comes out, usually in clinic, in about ten seconds.”

Surgery leaves an empty space inside. That space fills up with fluid unless drained.

• Prevents seroma: Surgical sites collect blood and lymph in the days after. Without a drain, this pools into a seroma. A drain stops that fluid before it ever accumulates.
• Lowers infection: Stagnant fluid is the perfect food for bacteria. Drain the fluid out continuously and the chance of a wound infection drops sharply.
• Eases pressure: Fluid trapped under the skin causes swelling, pain and pulls at the stitches. The drain keeps tension off the healing wound.
• Helps wound healing: Tissues knit back together better when they’re held in close contact. Drains pull the layers closer and keep them there.

For patients whose surgery uses keyhole precision through small incisions, robotic cancer surgery often needs smaller or fewer drains thanks to less tissue disruption.

Output decides it, not the calendar. Removal itself is quick.

• Output drops: The drain comes out when daily fluid is under 30 ml for two days in a row. Some breast and head and neck cases need a bit more, some abdominal cases less.
• Wound check: The surgeon looks at the wound first. No infection, no leakage, healing looking on track? The drain comes out.
• Removal moment: A snip of the holding stitch. A quick pull. Done in seconds. Most patients feel a tugging sensation, not real pain. No anaesthesia needed.
• After removal: A small dressing over the site. A tiny bit of clear fluid for a day or two is normal. Shower allowed once the site is dry.

For everything else about recovery after surgery including diet, dressings and when to resume normal activity, our guide on post surgery care walks through the full recovery.

Dr. Sandeep Nayak has spent 24 years in surgical oncology. He holds DNB qualifications in Surgical Oncology and General Surgery and a fellowship in Laparoscopic and Robotic Onco Surgery. He places drains only when surgery genuinely needs them, removes them as soon as output drops to safe levels, and uses minimally invasive techniques that often reduce or eliminate drain need entirely.

That careful judgement on when drains are needed and when they’re not is what separates a thoughtful surgical plan from a routine one. Every case at MACS Clinic goes through tumour board review, where the surgical plan is set together. Call +91 8104310753 to book your consultation.

Ascites is a build up of fluid inside the abdominal cavity. When it’s linked to cancer, it’s called malignant ascites. It happens most often in ovarian, liver, colorectal, stomach, pancreatic and breast cancer, usually when the disease has spread to the abdominal lining. The fluid builds up because the tumour irritates the peritoneum, blocks lymphatic drainage or damages the liver’s protein balance. Treatment focuses on draining the fluid, controlling the underlying cancer and managing symptoms.

According to Prof. Dr. Sandeep Nayak, Surgical Oncologist in India, “Ascites is one of the clearest signs that cancer has reached the peritoneal cavity, and it changes how we think about treatment. Draining the fluid relieves symptoms quickly, but the real focus has to be on treating the cancer driving it, otherwise the fluid keeps coming back.”

Several mechanisms can trigger it, and most are tied to cancer behaviour.

• Peritoneal spread: When cancer cells reach the abdominal lining, they cause inflammation and leaky blood vessels. Fluid and protein pour into the cavity instead of staying in circulation.
• Liver involvement: Cancer in or around the liver pushes up portal pressure. The liver also makes less albumin, which is what normally holds fluid in the bloodstream.
• Lymph blockage: Tumours can block lymphatic drainage channels in the abdomen. Without proper drainage, fluid that would normally be reabsorbed builds up instead.
• Tumour signals: Some tumours release chemicals that increase blood vessel leakiness. The result is more fluid escaping into the peritoneal space.

For patients whose cancer can be surgically controlled, robotic cancer surgery brings precise tumour removal that often reduces the fluid burden meaningfully.

Diagnosis is straightforward. Treatment is layered, depending on cause and stage.

• Paracentesis: A small needle drains fluid from the abdomen. It relieves symptoms in around 90 percent of patients. The fluid is also tested for cancer cells under cytology.
• Diuretics added: Tablets like spironolactone or furosemide help the kidneys clear extra fluid. Works better when liver involvement is part of the cause.
• Cancer directed: Chemotherapy, targeted therapy or HIPEC can shrink the underlying cancer. When the cancer responds, ascites often slows or stops returning.
• Long term drains: When fluid keeps coming back quickly, a tunnelled catheter lets the family drain at home. Reduces hospital visits significantly.

For patients whose peritoneal cancer is being managed with cytoreductive surgery, our blog on HIPEC surgery walks through outcomes and what survival actually depends on.

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 approaches ascites as a sign that needs both immediate relief and root cause treatment, combining paracentesis, diuretics and cancer directed therapy including HIPEC and PIPAC where appropriate.

That dual focus on comfort and underlying disease is what separates real ascites management from symptomatic drainage alone. Every case at MACS Clinic goes through tumour board review, where the treatment plan is set together. Call +91 8104310753 to book your consultation.

Node positive cancer means that cancer cells have spread from the original tumour into one or more nearby lymph nodes. It usually puts the cancer at stage 2 or 3, not stage 4, which would require spread to distant organs. The number of involved nodes, where they sit and how the tumour behaves all shape the treatment plan. Node positive cancers remain very treatable, and in many cases, curable with the right combination of surgery and follow up therapy.

According to Prof. Dr. Sandeep Nayak, Surgical Oncologist in India, “Node positive isn’t a verdict, it’s information. It tells the team how far the cancer has travelled inside its own neighbourhood, which then shapes whether we need to add radiation, chemo or both alongside surgery. Many node positive cancers still have excellent outcomes when the full plan is properly executed.”

The finding gives the team essential information about how the cancer is behaving.

• Spread starting: Cancer cells have escaped the original tumour and reached the closest filter system, the lymph nodes. It hasn’t reached distant organs.
• Stage shifts: Node involvement typically moves the staging from 1 to 2 or 3. Stage 4 needs distant organ involvement, which node positive alone doesn’t mean.
• Number matters: One small involved node carries far less weight than five large involved nodes. The count and size strongly shape treatment intensity.
• Behaviour clue: Node positivity hints at how active and aggressive the tumour is. This information feeds directly into chemotherapy and radiation planning.

For patients whose plan includes surgical removal of the tumour and involved nodes, robotic cancer surgery brings precise dissection in tight anatomical areas.

Treatment becomes more layered, but stays focused and effective.

• Surgery first: The tumour and involved nodes usually come out together. Clean margins on both the primary tumour and the affected nodes are the goal.
• Chemo added: Most node positive cases get chemotherapy alongside surgery. It deals with any microscopic cells that may have escaped further than the imaging picked up.
• Radiation often: Radiation to the lymph node area is common, particularly in breast cancer with multiple involved nodes. It prevents local recurrence.
• Targeted therapy: For specific cancers like HER2 positive breast or BRAF mutant melanoma, targeted drugs add another precise layer of treatment beyond chemo.

For breast cancer patients wanting to understand exactly how involved lymph nodes are managed surgically, our blog on lymph node surgery in breast cancer walks through the decisions.

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 treats node positive cancers with the same calm, structured approach used in major centres worldwide, surgery first where indicated, followed by carefully sequenced chemo, radiation and targeted therapy as the case requires.

That structured, multi modal approach is what gives node positive patients their best chance at long term outcomes. Every case at MACS Clinic goes through full tumour board review, where the treatment plan is set together. Call +91 8104310753 to book your consultation.
