Proton Therapy
Protons release their energy at the tumour and stop, reducing the dose to normal organs — used for selected head and neck, skull base, breast and gynaecological cancers.
Dr. Sapna Nangia is a highly experienced Radiation Oncologist with extensive expertise in the diagnosis and treatment of cancer using advanced radiation therapy techniques. Her areas of clinical expertise include Head & Neck Cancer, Breast Cancer, and other cancers requiring precision radiation treatment. She has experience with advanced techniques such as Intensity-Modulated Radiation Therapy (IMRT), Image-Guided Radiation Therapy (IGRT), and Proton Therapy.
Radiation techniques, the cancers treated with them, and the planning and consultation that decide which one is appropriate.

Protons release their energy at the tumour and stop, reducing the dose to normal organs — used for selected head and neck, skull base, breast and gynaecological cancers.

Comprehensive radiation treatment planning and management for different types and stages of cancer.

Intensity-Modulated Radiation Therapy shapes and modulates the dose to the treatment target. Dr. Nangia helped establish one of India’s early IMRT programmes.

Image-Guided Radiation Therapy uses imaging during treatment for accurate positioning, and daily IGRT reduces the volume of normal tissue that receives radiation.

Highly precise radiation technique used to deliver focused radiation to selected tumours or abnormal areas.

Highly focused radiation in a few sessions for oligometastatic disease — a limited number of liver, lung, bone or lymph nodal metastases.

Image guidance with highly modulated delivery: less dry mouth and swallowing difficulty in head and neck cancers, and bowel and bladder sparing in gynaecological cancers.

Internal radiation placed close to or within the treatment area, including advanced image-guided brachytherapy.

Oral cavity, oropharynx, salivary gland, nasopharyngeal, laryngeal and hypopharyngeal cancers.

Clival chordoma, adenoid cystic, temporal bone and paranasal sinus cancers, including SNEC and SNUC.

Cardiac-sparing radiation including DIBH and proton therapy, for left-sided, post-mastectomy and locally advanced disease.

Cervical and endometrial cancers, treated with tomotherapy and image-guided brachytherapy.

Individualised treatment planning based on tumour location, cancer type, treatment goals, and surrounding healthy organs.

Detailed consultation to understand the diagnosis and determine whether radiation therapy may be appropriate as part of the treatment plan.
Her approach focuses on personalised radiation treatment planning, with careful consideration of the type, location, and stage of cancer. She also has expertise in advanced radiation techniques designed to deliver precise treatment while helping protect surrounding healthy tissues.
Which technique is used follows from that assessment — not the other way round.
A consultation reviews the diagnosis and the imaging, and explains whether radiation therapy — and which technique — may be appropriate in your case.
