Dr. Nisha Thottam Vishnu completed her MBBS and medical internship at G.R. Medical College, Gwalior, followed by MD in Radiation Oncology from J.K. Cancer Institute, GSVM Medical College, Kanpur. She subsequently completed fellowship training in advanced radiation oncology techniques at Mazumdar Shaw Cancer Centre, Bengaluru. She also holds certification from the Educational Commission for Foreign Medical Graduates (ECFMG), USA.
Her professional background includes research experience at the Uniformed Services University of the Health Sciences in Bethesda, USA, and the National Institutes of Health. Her research activities involved molecular genetics, including comparative genomic hybridization studies. This international research experience complements her clinical interests in precision oncology, advanced treatment planning and cancer radiotherapy.
Dr. Nisha Thottam Vishnu specializes in radiation treatment for selected breast cancers, gynecological cancers, head and neck cancers, brain tumors and other malignancies requiring radiation oncology care. She uses modern treatment planning principles to deliver radiation doses to cancerous tissues while attempting to reduce unnecessary exposure to surrounding healthy structures.
Her expertise includes Intensity-Modulated Radiation Therapy (IMRT), Image-Guided Radiation Therapy (IGRT), Volumetric Modulated Arc Therapy (VMAT), Stereotactic Radiosurgery (SRS), Stereotactic Radiotherapy (SRT), Stereotactic Body Radiation Therapy (SBRT) and Tomotherapy. These specialized techniques may be considered according to tumor location, cancer stage, treatment objectives and available equipment.
Dr. Nisha Thottam Vishnu also has advanced experience in brachytherapy, a form of radiation treatment in which a radiation source is positioned within or close to the treatment area. Her documented expertise includes intracavitary, intravaginal, interstitial and intraluminal brachytherapy. These techniques are particularly relevant to selected gynecological malignancies and other cancers requiring highly localized radiation treatment.
Her clinical interests include personalized radiotherapy planning for breast and gynecological cancers and the treatment of complex head and neck tumors and brain lesions. Radiation therapy may be provided as a primary treatment, before or after surgery, alongside systemic cancer treatment or for symptom relief, depending on the individual diagnosis and multidisciplinary treatment recommendation.
Dr. Nisha Thottam Vishnu has held clinical positions at Fortis Hospital, Bengaluru, Medanta – The Medicity, Gurugram, and other healthcare institutions. Her experience also includes participation in clinical research, academic conferences and professional education programs involving radiation oncology and brachytherapy.
She has contributed to research publications and presentations relating to radiotherapy techniques, imaging-based treatment planning and molecular medicine. Her professional achievements include recognition for innovation in brachytherapy at the National Brachytherapy Conference in 2019, as reported by KIMS Hospitals.
Dr. Nisha Thottam Vishnu focuses on individualized cancer treatment planning, accurate radiation delivery and management of treatment-related side effects. Patients requiring radiotherapy for breast cancer, gynecological cancers, brain tumors, head and neck cancers and other appropriate malignancies can consult her for specialized radiation oncology evaluation and treatment recommendations in Bangalore.
Dr. Nisha Thottam Vishnu specializes in radiation oncology, using carefully planned radiation treatments for selected cancers. Her expertise includes precision radiotherapy, stereotactic techniques and brachytherapy. Treatment recommendations depend on tumor type, stage, location and multidisciplinary cancer care planning.
She has expertise in radiotherapy planning for breast cancer patients. Radiation may be recommended after breast-conserving surgery or selected mastectomies to reduce the risk of local recurrence. Techniques such as IMRT, IGRT and VMAT may be used according to the patient's treatment requirements.
Dr. Nisha Thottam Vishnu provides radiation oncology care for selected cervical cancer cases. Treatment may involve external beam radiotherapy, concurrent chemotherapy under medical oncology supervision and brachytherapy to deliver targeted radiation doses to the affected area.
Her clinical expertise includes radiation treatment planning for gynecological cancers such as cervical and endometrial cancer. Depending on the diagnosis, treatment may involve external beam radiotherapy, intracavitary brachytherapy, intravaginal brachytherapy or other appropriate radiation techniques.
She provides specialized radiation treatment planning for selected head and neck cancers. Advanced techniques such as IMRT and IGRT can help shape radiation doses around complex anatomy while reducing unnecessary exposure to nearby healthy tissues.
Dr. Nisha Thottam Vishnu has expertise in advanced radiation techniques used for selected brain tumors and intracranial lesions. Stereotactic radiosurgery and stereotactic radiotherapy may be considered according to tumor size, location, diagnosis and surrounding critical structures.
Radiotherapy for lung cancer may involve conventional external beam treatment or specialized techniques such as stereotactic body radiation therapy. Treatment selection depends on tumor stage, lung function, treatment goals and the patient's overall condition.
Radiation therapy is an established treatment option for selected prostate cancers. Techniques such as IMRT, IGRT and other precision radiation approaches may be used to deliver treatment while limiting exposure to nearby structures such as the bladder and rectum.
Dr. Nisha Thottam Vishnu has documented expertise in IMRT, an advanced radiation technique that adjusts the intensity of radiation beams to achieve planned dose distributions. It is used for selected cancers where careful protection of nearby healthy structures is particularly important.
IGRT uses imaging during the treatment process to verify patient positioning and the location of the treatment target. This approach supports accurate radiation delivery and may be used alongside techniques such as IMRT or VMAT.
Dr. Nisha Thottam Vishnu has expertise in VMAT, an advanced external beam radiotherapy method that delivers modulated radiation while the treatment equipment rotates around the patient. It can provide conformal dose delivery in selected clinical situations.
She has expertise in stereotactic radiation techniques used for precisely targeted treatment of selected brain lesions and other conditions. SRS generally delivers treatment in a single session, while fractionated stereotactic radiotherapy uses multiple treatment sessions when clinically appropriate.
SBRT is a high-precision radiation technique that delivers concentrated radiation doses in a limited number of sessions for selected tumors outside the brain. Suitability depends on tumor size, location, nearby organs and the patient's clinical condition.
Dr. Nisha Thottam Vishnu has documented expertise in Tomotherapy, which combines rotational radiation delivery with image guidance. This technique may be used for selected cancers requiring complex radiation dose distributions and precise treatment planning.
She has expertise in intracavitary and intravaginal brachytherapy for selected gynecological cancers. These procedures place a radiation source inside a body cavity or applicator close to the treatment site to deliver localized radiation doses.
Dr. Nisha Thottam Vishnu has experience in interstitial and intraluminal brachytherapy techniques. These methods involve positioning radiation sources within tissues or body passages for selected cancers, according to tumor anatomy and treatment planning requirements.
Radiation oncology care includes monitoring treatment-related symptoms such as fatigue, skin reactions and site-specific side effects. Appropriate supportive treatment, patient education and follow-up are important parts of maintaining safety and comfort during cancer radiotherapy.
