Radiation therapy or radiotherapy uses high energy photons to destroy the cancerous cells. Each radiotherapy plan is unique to the individual patient and personalised for each patient to deliver as much radiation dose to the tumour and as low as possible dose to the surrounding healthy tissues.

Our Cancer Centre is equipped with Accuray Tomo Therapy system. Tomotherapy integrates computerised tomography (CT) imaging with radiation therapy to deliver radiation treatment with speed and precision while reducing radiation exposure to surrounding healthy organs.

      ·         Image-Guided Intensity Modulated Radiation Therapy (IG-IMRT)

       IG-IMRT is the use of three-dimensional (3D) imaging guidance to improve the precision and accuracy of treatment delivery. IMRT is a safe and painless radiation technique that delivers highly precise radiation dose to the cancer effectively while limiting the damage to the healthy tissues nearby. This increases the chance for a cure and lessens likelihood of side effects. IG-IMRT is used to treat a wide range of cancers such as the cancers of the head and neck, breast, lung, cervix, endometrium, prostate, rectum and other sites.

·         Stereotactic Radiosurgery (SRS)
 SRS is a non-invasive procedure that delivers precise and very high dose of radiation in treating functional and non-functional abnormalities or small tumours of the brain.

·         Stereotactic Body Radiation Therapy (SBRT)
 SBRT is a specialized radiation therapy that delivers extremely precise and high radiation dose to small tumors in the lung, abdomen or spine.

What Can I Do to Take Care of Myself During Radiation Therapy

During radiation therapy, you need to take good care of yourself. Your cancer care team will give you tips on how to do this but here are some things that you should do:

·         Get a lot of rest. You may feel more tired than normal. This can last several weeks or months after your treatment ends. Sometimes the fatigue can last longer.

·         Eat healthy foods. Your cancer care team can work with you to make sure you’re eating the right foods to get what your body needs. They may have tips to help with side effects if your stomach or throat is in the area being treated.

·         Take care of the skin in the treatment area. Clean the skin each day with warm water and a mild soap that your team says is OK to use. Don’t use anything else on the treated skin unless your cancer care team tells you it’s OK.

·         Tell your cancer care team about all medicines you are taking. If you take any medicines, even aspirin, herbs, or vitamins, let your team know before you start radiation.

 

Good nutrition during cancer treatment can help patients to:

·         Feel better.

·         Keep up their strength and energy.

·         Maintain weight and the body’s store of nutrients.

·         Better tolerate treatment-related potential side effects.

·         Lower the risk of infection.

·         Heal and recover faster.

1. Chemotherapy

Chemotherapy uses pharmaceutical drugs to treat cancer patients. It is a systemic therapy which is able to damage the cancer cells at almost any anatomic location in the patient’s body.

Chemotherapy drugs damage cells as they divide. This makes the drugs effective against cancer cells, which divide much more rapidly than most normal cells do. Chemotherapy is most often given via a vein (intravenously). It is sometimes given in other ways, such as orally in tablets forms.

Chemotherapy is commonly given in courses (cycles), with rest periods in between. This allows normal cells to recover and your body to regain its strength. If your body needs more time to recover, your next cycle may be delayed. Your doctor will discuss your treatment plan with you.

Sometimes people have chemotherapy over 6-12 months, but it’s possible to have it for a shorter or longer period. Maintenance treatment (to prevent the cancer coming back) and palliative treatment (to control the cancer or relieve symptoms) may last many months or years. 

 

 2. Hormonal Therapy

Hormonal therapy slows or stops the growth of cancer that uses specific hormones to grow. It can be given in pills or injection or with surgery to remove the hormone producing organ. It is widely used to treat prostate cancers and breast cancers

 

3. Targeted Therapy

Targeted therapy inhibits the growth of cancer cells by interfering with specific genes, proteins or tissue environment that contribute to cancer growth and survival. Targeted therapy is usually used together with chemotherapy and other treatments. 

 

4. Immunotherapy

Immunotherapy works by marking the cancer cells and therefore allowing the immune system to find and destroy them; or by boosting your immune system to better destroy the cancer cells.

 

 

Surgery

Surgical oncology focuses on using surgery to diagnose, stage and treat cancer. Palliative surgeries may also be performed to help control pain, increase a patient’s comfort level and manage cancer-related symptoms and side effects.
