The same principles of Cancer surgery, applied to the breast, uterus, cervix, ovary, kidney, bladder, prostate, skin, bone and soft tissue.
Dr Dinesh Mavinahalli Gangaiah is a surgical Oncologist at ARC Cancer Hospital, Bengaluru. Alongside GI and thoracic Cancer surgery, his work covers gastrointestinal, thoracic, breast, gynaecological, urological, skin, neuroendocrine, bone, and soft tissue Cancers, with every patient receiving treatment tailored to their disease, overall health, and long-term quality of life.
Cancer surgery is never just about removing a tumour. It is about making the right decision at the right time, choosing the most appropriate surgical approach, and ensuring that every step of treatment is guided by evidence, experience, and compassion.
At ARC Cancer Hospital, every patient’s treatment plan is discussed by the multidisciplinary Tumour Board before any treatment begins. Surgeons, medical Oncologists, radiation Oncologists, radiologists, pathologists, and other specialists come together to evaluate each case and determine the best course of action. This collaborative approach ensures that every patient benefits from collective expertise and receives care that is personalised, ethical, and evidence-based.
Wherever the Cancer begins, the aim stays the same: to provide safe, comprehensive, and Oncologically sound surgical care while preserving function, maintaining quality of life, and aiming for a safe and complete result for each patient.
| Cancer Type | Surgical Approach | Key Benefit of Minimally Invasive |
|---|---|---|
| Breast Cancer | Breast-conserving surgery (lumpectomy); modified radical mastectomy; skin and nipple-sparing mastectomy; axillary lymph node dissection; sentinel lymph node biopsy | Smaller incision; reduced blood loss; faster return to daily activity; Oncologically equivalent to open surgery |
| Cervical Cancer | Laparoscopic or robotic radical hysterectomy (Wertheim’s); pelvic lymph node dissection; fertility-sparing surgery (trachelectomy) in selected young patients | Robotic radical hysterectomy reduces blood loss; shorter hospital stay; better pelvic sidewall visualisation for nodal dissection |
| Uterus Cancer(Endometrial) | Laparoscopic or robotic total hysterectomy with bilateral salpingo-oophorectomy; pelvic and para-aortic lymph node dissection | Minimally invasive hysterectomy is now the international standard for endometrial Cancer; equivalent staging and survival with reduced morbidity |
| Ovarian Cancer | Laparoscopic staging and cytoreductive surgery for selected early-stage cases; interval debulking surgery after neoadjuvant chemotherapy | Minimally invasive staging and selected cytoreduction reduces recovery time before chemotherapy; early return to systemic treatment improves overall outcomes |
| Kidney Cancer(Renal Cell Carcinoma) | Laparoscopic or robotic partial nephrectomy (nephron-sparing); radical nephrectomy; cytoreductive nephrectomy for metastatic disease | Robotic partial nephrectomy achieves equivalent Oncological outcomes with maximal kidney function preservation, critical for Indian patients with diabetes or hypertension |
| Bladder Cancer | Transurethral resection of bladder tumour (TURBT); laparoscopic or robotic radical cystectomy with urinary diversion (ileal conduit or neobladder) | Minimally invasive radical cystectomy reduces blood loss and hospital stay; robotic intracorporeal neobladder construction achieves better functional outcomes |
| Prostate Cancer | Laparoscopic or robotic radical prostatectomy; nerve-sparing prostatectomy; pelvic lymph node dissection | Robotic prostatectomy is the gold standard for localised prostate Cancer, better 3D magnification enables precise nerve-sparing for functional preservation |
| Penile Cancer | Wide local excision; glansectomy with reconstruction; partial penectomy; inguinal lymph node dissection; sentinel lymph node biopsy | Organ-preserving surgery for early penile Cancer; glansectomy with skin graft reconstruction preserves penile shaft and urinary function |
| Skin Cancer(Melanoma and Non-Melanoma) | Wide local excision with adequate margins; sentinel lymph node biopsy; completion lymph node dissection; local flap reconstruction | Sentinel lymph node biopsy avoids unnecessary full lymph node dissection in the majority of patients who will have a negative sentinel node |
| NeuroendocrineTumours (NETs) | Laparoscopic or robotic resection of primary NET (pancreatic, small bowel, appendix, rectal); liver resection for selected NET hepatic metastases | Minimally invasive NET resection preserves surrounding organ function; pancreatic NETs treated with enucleation or distal pancreatectomy laparoscopically where possible |
| Bone and SoftTissue Tumours | Wide excision of soft tissue sarcoma with clear margins; limb-salvage surgery; resection of benign bone tumours; chest wall sarcoma resection | Limb-salvage surgery for extremity sarcoma achieves equivalent survival to amputation with functional limb preservation, the standard of care for most extremity sarcomas |
Breast Cancer is the most common Cancer in Indian women, and surgery remains the cornerstone of curative treatment for localised and locally advanced breast Cancer. Dr Dinesh Mavinahalli Gangaiah performs the full spectrum of breast Cancer surgery at ARC Cancer Hospital, from breast-conserving lumpectomy to modified radical mastectomy, with sentinel lymph node biopsy and axillary lymph node dissection for nodal staging and management.
Every breast Cancer surgical plan at ARC Cancer Hospital is reviewed at the Multidisciplinary Tumour Board, with medical Oncology input on neoadjuvant chemotherapy eligibility, radiation Oncology input on post-operative radiation fields, and pathology review of molecular subtype and receptor status.
Cervical Cancer is the second most common Cancer in Indian women, with an estimated 1.23 lakh new cases diagnosed annually in India. Surgery is the primary curative treatment for Stage I and selected Stage II cervical Cancer. Dr Dinesh Mavinahalli Gangaiah performs minimally invasive radical hysterectomy, the Wertheim’s procedure, through laparoscopic and robotic platforms at ARC Cancer Hospital.
Endometrial Cancer, Cancer of the inner lining of the uterus, is the most common gynaecological Cancer in urban Indian women, rising in parallel with increasing rates of obesity, diabetes, and hormonal changes associated with the urban lifestyle transition. Surgical staging and hysterectomy is the definitive treatment for most endometrial Cancers.
Ovarian Cancer is the third most common gynaecological Cancer and the most lethal, because it is frequently diagnosed at an advanced stage. Surgery plays a central role in both diagnosis and treatment: staging surgery to confirm extent of disease, and cytoreductive (debulking) surgery to remove as much tumour as possible before or after chemotherapy.
Ovarian Cancer surgery planning is one of the most nuanced decisions in gynaecological Oncology, the choice between upfront debulking and neoadjuvant chemotherapy followed by interval surgery is determined by the extent of peritoneal disease, the patient’s performance status, and the likelihood of achieving complete cytoreduction. Every ovarian Cancer patient at ARC Cancer Hospital is reviewed at the Multidisciplinary Tumour Board before a surgical plan is confirmed.
Kidney Cancer, predominantly renal cell carcinoma (RCC), is increasingly diagnosed incidentally on CT or ultrasound performed for other reasons. Surgical resection is the primary curative treatment for localised renal Cancer. Dr Dinesh Mavinahalli Gangaiah performs laparoscopic and robotic nephrectomy at ARC Cancer Hospital, with a strong emphasis on nephron-sparing partial nephrectomy wherever Oncologically appropriate.
For Indian patients with kidney Cancer who also have diabetes or hypertension, a common combination, nephron-sparing partial nephrectomy is particularly important; these patients have higher baseline risk of progressive kidney disease, and preserving maximum kidney tissue has long-term implications for cardiovascular health and avoidance of dialysis.
Bladder Cancer is the most common Cancer of the urinary tract. Surgery is the primary treatment for both non-muscle-invasive and muscle-invasive bladder Cancer. Dr Dinesh Mavinahalli Gangaiah performs the full spectrum of bladder Cancer surgery at ARC Cancer Hospital, from endoscopic TURBT for early disease to laparoscopic and robotic radical cystectomy for muscle-invasive Cancer.
Prostate Cancer is the fastest-rising Cancer in Indian men, with incidence projected to double by 2040. Radical prostatectomy, surgical removal of the prostate, is one of the two definitive curative treatments for localised prostate Cancer (the other being radiation therapy). Dr Dinesh Mavinahalli Gangaiah performs laparoscopic and robotic radical prostatectomy at ARC Cancer Hospital.
Penile Cancer, predominantly squamous cell carcinoma, is one of the most feared Cancer diagnoses among Indian men, primarily because of the fear of penectomy. At ARC Cancer Hospital, organ preservation is the guiding principle of penile Cancer surgery, and for the majority of patients with early-stage disease, the penis can be preserved while achieving complete Cancer clearance.
Every penile Cancer patient at ARC Cancer Hospital is evaluated for organ-preserving surgery before more extensive surgery is considered. The Multidisciplinary Tumour Board reviews tumour stage, imaging findings, and biopsy results to determine the appropriate surgical approach for each individual patient.
Skin Cancer, including basal cell carcinoma, squamous cell carcinoma, and melanoma, is among the most surgically treatable of all Cancers when detected early. Dr Dinesh Mavinahalli Gangaiah performs skin Cancer excision and the surgical management of melanoma, the most Oncologically significant of the skin Cancer types, at ARC Cancer Hospital.
Neuroendocrine tumours, often called NETs or carcinoid tumours, are a heterogeneous group of tumours arising from neuroendocrine cells found throughout the body. The most common sites are the pancreas, small intestine, appendix, rectum, and lung. NETs range from slow-growing, well-differentiated tumours that may be managed conservatively to aggressive, poorly differentiated neuroendocrine carcinomas requiring multimodal treatment.
Bone and soft tissue tumours, collectively called musculoskeletal Oncology, are a diverse group of rare tumours requiring highly specialised surgical management. The primary principle of soft tissue sarcoma surgery is complete resection with clear margins, achieved through limb-salvage surgery in the vast majority of patients, avoiding amputation while maintaining equivalent Oncological outcomes.
Soft tissue sarcoma is one of the Cancers where multidisciplinary treatment planning is most critical, neoadjuvant radiation therapy before surgery, or adjuvant radiation after surgery, significantly reduces local recurrence risk for high-grade tumours; this sequencing is determined at the ARC Cancer Hospital Tumour Board.
Whatever the Cancer type, breast, gynaecological, urological, skin, neuroendocrine, or musculoskeletal, the approach at ARC Cancer Hospital is identical: every patient is reviewed at the Multidisciplinary Tumour Board before any treatment decision is finalised. No surgery is planned on the basis of a single specialist’s opinion alone.
Dr Dinesh Mavinahalli Gangaiah practises at ARC Cancer Hospital, Bengaluru, Dr MH Marigowda Road, Lakkasandra, Hombegowda Nagar, Bengaluru, 560027. He sees patients from across Bengaluru and Karnataka, and from Tamil Nadu, Andhra Pradesh, Telangana, and Kerala for surgical Oncology consultations and Cancer surgery.
Yes, and for endometrial Cancer, minimally invasive surgery is now the international standard of care. Multiple large randomised controlled trials have confirmed that laparoscopic and robotic staging and hysterectomy for endometrial Cancer achieves equivalent Oncological outcomes to open surgery, with fewer complications, shorter hospital stay, and faster recovery. For cervical Cancer, robotic radical hysterectomy achieves equivalent Cancer control to open Wertheim’s procedure with 70% less blood loss and a significantly shorter recovery. Dr Dinesh Mavinahalli Gangaiah performs laparoscopic and robotic radical hysterectomy for cervical Cancer and laparoscopic/robotic hysterectomy with staging for endometrial Cancer at ARC Cancer Hospital as the standard approach for eligible patients.
Sentinel lymph node biopsy (SLNB) is a technique that identifies and removes only the first-draining lymph node from a tumour, the ‘sentinel’ node, rather than removing an entire lymph node region. The principle is that if Cancer has spread to the regional lymph nodes, it will have reached the sentinel node first; if the sentinel node is negative, the remaining nodes are very unlikely to contain metastases. SLNB is used in breast Cancer, melanoma, penile Cancer, cervical Cancer, and endometrial Cancer. The key advantage over full lymph node dissection is a reduced risk of lymphoedema, the chronic limb swelling that can follow removal of large numbers of lymph nodes, while providing equivalent staging accuracy. At ARC Cancer Hospital, SLNB is performed using a combination of radiotracer and/or blue dye for reliable sentinel node identification.
No: for localised prostate Cancer, both radical prostatectomy (surgery) and definitive radiation therapy achieve equivalent long-term Cancer control. The choice between them is not about which is more effective, it is about which side effect profile better matches your priorities, age, and lifestyle. Surgery is associated with risks of urinary incontinence (most men recover with pelvic floor physiotherapy) and erectile dysfunction. Radiation therapy is associated with gradual urinary and bowel changes. At ARC Cancer Hospital, both options are presented and discussed at the Multidisciplinary Tumour Board before any recommendation is made. No patient of Dr Dinesh’s is recommended prostate surgery without the radiation option being fairly and fully presented.
Do not have it biopsied or excised at a non-specialist centre. This is the most important advice in soft tissue sarcoma management. An inadvertent excision of a soft tissue sarcoma without appropriate margins, performed at a general surgical centre without awareness that the lump might be a sarcoma, makes subsequent curative surgery significantly more difficult and may worsen prognosis. Any soft tissue lump that is: enlarging; greater than 5 cm; deep to the muscle fascia; hard or firm; or associated with pain, warrants MRI before any surgical procedure, and specialist surgical Oncology review at a centre equipped for soft tissue sarcoma management. Please contact Dr Dinesh Mavinahalli Gangaiah at ARC Cancer Hospital for assessment before any excision is performed.
MCh (Magister Chirurgiae) in Surgical Oncology is a three-year superspeciality postgraduate surgical training programme in India dedicated exclusively to the surgical treatment of Cancer, offered at a small number of Cancer centres in India. It follows the MS in General Surgery and is the superspeciality qualification in Cancer surgery in India. An MCh Surgical Oncologist has trained for three years in the Oncological principles, margin assessment, lymph node management, reconstruction, staging, and multimodal treatment planning; that are specific to Cancer surgery, as distinct from general surgery. Dr Dinesh Mavinahalli Gangaiah holds an MS and an MCh in Surgical Oncology, meaning his entire surgical training has been focused on Cancer, not divided between Cancer and other surgical conditions.
