How can you prepare?

Our Radiation Oncology team will walk you through the entire process before you receive Radiotherapy.

Immobilisation: Immobilization devices such as aquaplast moulds, casts, and headrests are used in radiation therapy to make sure that the patient stays in the correct position over the course of treatment. If a patient is not immobilised properly, then he/she is at risk for improper treatment and unwanted side effects.

Planning Computed Tomography (CT) scan: To determine the exact location of the cancer affected area to be treated, you will have to undergo CT scans.

Radiotherapy Treatment planning & Quality Assurance (QA): The acquired CT images will be transferred to advanced algorithm based treatment planning software systems for accurate radiation dose calculations and dose evaluation. This process achieves the aim of Radiotherapy by delivering the maximum dose to the tumour and minimum dose to normal tissues

Treatment Execution:

Finally, after passing QA criteria specified by the Medical Physicists, the plan will be approved for treatment execution by the skilled and experienced Radiotherapy Technologists. However, the first day treatment setup will be supervised by a Radiation Oncologist and Medical Physicist. During the treatment the Linac moves around as you lie on a table, delivering radiation from various angles through the dynamically modified apertures to deliver the radiation precisely.

During the treatment delivery:

External beam radiation is generally delivered as an outpatient procedure, 5 days/ week for a set period of time.

Each treatment session should last between 10-30 minutes.

A single treatment may be used in some cases to help relieve pain or other symptoms associated with more advanced cancers based upon the Radiation Oncologist’s decision.

During the treatment, you will lie still and breathe normally. You may be asked to hold your breath while the machine administers treatment in some cases of lung or breast cancer.

The team will remain nearby in a room equipped with video and audio connections, allowing you to communicate with one another. If you are uncomfortable, you should speak up, but you should not experience any pain during your radiation therapy session.

Emotional and Mental needs

After Treatment | After Care

After undergoing radiotherapy, patients may be advised to take some precautions and follow certain guidelines for aftercare, such as:

  • Rest and recovery: It’s essential to rest as much as possible after radiotherapy treatment to allow your body to heal. It is also important to avoid any strenuous activities and get adequate sleep.
  • Follow-up appointments: Attend all follow-up appointments with your healthcare team. This allows your doctor to monitor your progress and manage any side effects that may arise.
  • Maintain good nutrition: Eat a healthy and balanced diet to help your body recover from radiation therapy. Foods high in protein, vitamins, and minerals are essential.
  • Stay hydrated: Drink plenty of fluids, especially water, to help flush out any toxins that may be lingering in your body after treatment.
  • Skin care: If the radiation therapy has affected your skin, it’s important to keep the area clean and dry. Avoid using harsh soaps or scrubs and wear loose-fitting clothing.
  • Pain management: If you experience any pain or discomfort after treatment, speak with your healthcare provider. They may be able to prescribe pain medication or recommend other methods of pain management.
  • Exercise: Low-impact exercises, such as walking, can help improve circulation and prevent blood clots. However, it’s important to consult with your doctor before starting any new exercise regimen.
  • Emotional support: Radiotherapy treatment can be emotionally draining. It’s essential to seek emotional support from friends, family, or a counsellor to help you cope with any feelings of anxiety or depression.
  • Avoid smoking and alcohol: Smoking and alcohol can interfere with your body’s ability to heal. It’s important to avoid them during your recovery period.
  • Monitor side effects: Keep a record of any side effects you experience and notify your healthcare provider if they persist or worsen over time

It’s essential to follow these aftercare instructions carefully to ensure the best possible outcome and minimise any potential risks or complications. If you have any questions or concerns about your aftercare plan, be sure to discuss them with your healthcare provider.

Radiation therapy is not typically painful, but some patients may experience slight manageable discomfort or tenderness in the treatment area.

Yes, radiation therapy is often used in combination with other treatments such as surgery and chemotherapy.

The success rate of radiation therapy can vary depending on the type and stage of cancer being treated. It is often used in combination with other treatments, and the overall success rate can be quite high.

Cervical cancer is the second most common type of cancer in women in India. The HPV vaccine is the only effective vaccine available against this type of cancer. It is recommended for all girls between 9 to 16 years of age along with a catch up vaccination between the ages 15-45 years.

MGM Healthcare, in association with Rotary Club, is organising a HPV Vaccination Drive and invites teenage girls to come and get vaccinated on 26th February, 2022. Aswatha Biju, Youngest Palaeontologist and Pradhan Mantri Rashtriya Bal Puraskar award winner, will be taking her shot as a precaution against Cervical Cancer

If you have cervical cancer, there are several ways your doctor can treat your condition. Which one they recommend will depend on what type of cervical cancer you have, your age, and whether or not you might want to have children in the future. Many cervical cancer patients undergo surgery, and there are a few different types that may be used for treatment.

Dr Balaji Ramani, Senior Consultant, Oncology, at MGM Cancer Institute & MGM Healthcare talks about the treatment options available now.

Cervical cancer is the second most common cancer in women worldwide. When a lesion is visible with the naked eye, conization is contraindicated, and a cervical biopsy will usually provide the diagnosis. Screening tests can help detect cervical cancer and precancerous cells that may one day develop into cervical cancer. The diagnosis leads to the treatment and management of the disease.

If you were to be diagnosed with cancer, how do you think you would feel? It would depend on the stage of cancer of course, but there’s a good chance that no matter the details, the word “cancer” would make the diagnosis much more frightening. Frightening enough, in fact, to do you as much harm, or more, than the disease itself.

There has been a lot of progress in medical science and more options now available than there were even 5 years ago. Today doctors better understand how to find many cancers in the early stages. They also have more treatments to try if one doesn’t work.

Women are more likely than men to develop lung cancers that are unrelated to smoking. Everyone shares the same risk factors for developing lung cancer, regardless of sex. This is especially true of chronic exposure to tobacco smoke, which is responsible for 85 to 90 percent of lung cancer diagnoses overall.

Dr Shubham Sharma, Consultant, Interventional Pulmonology discusses about lung cancer is affecting the female population & what can be done about it.

Years old theory states that hot liquids such as coffee or tea could destroy the inner lining of the esophagus, requiring the cells to continually regenerate. But how far is it correct? Should we stop starting out day with the sip of hot tea/coffee.

Let’s find the truth with our expert Dr Sivaram Ganesamoni, Senior Consultant, Oncology, MGM Cancer Institute. Learn from him that how hot beverages can\cannot affect our oral cavity.

Lung cancer is one of the commonest cancers and cause of cancer related deaths all over the world. Cancer can grow in your body for a long time — years — before you know it’s there. Lung cancer often doesn’t cause symptoms in early stages. While there are many factors that can increase your risk of lung cancer, smoking any kind of tobacco products, including cigarettes, cigars or pipes is the biggest single risk factor. The treatment will depend on the type of lung cancer you have, where it is, how far it’s spread and many other factors.
