Cancer of lung, head & neck, prostate, and breast are effectively treated with radiation therapy. Lung cancer radiation therapy uses powerful X-rays to kill cancer cells or to stop them from growing. Radiation can also be used before lung cancer surgery to reduce the size of the tumor or after surgery to kill the cancer cells in the lungs.
Some of the common symptoms of cancer are listed below. If you have any of these symptoms, consult an oncologist:

The below-listed popular procedures that Dr. Lijiya Pushpan performs are:
Proton therapy is safer and more effective than radiation therapy because it delivers a high dose to a specific area. A radiologist uses a beam of protons to deliver a dose of radiation therapy for the treatment of cancer. It destroys cancer cells and causes less damage compared to traditional radiation. This procedure is also painless and noninvasive. CyberKnifie is another powerful radiation therapy used for cancer treatment. It is a lightweight linear accelerator placed on a robotic arm. Real-time images allow patient movement tracking with high accuracy. The CyberKnife also uses real-time X-rays to find the exact position of the lesion during treatment.

Radiation oncologists use the therapeutic properties of radiation to treat cancer. They understand cancer as a disease, its cause, and patterns of spread. Radiation oncologists also determine how radiation can fit in the general scheme of treatment. Radiation oncologists also spend much time planning and performing radiation procedures. Planning plays a significant role in cancer treatment, as radiation has become more targeted. Radiation oncologists remain in touch with cancer patients post-treatment to keep a track of recovery.
Below are some tests that a radiation oncologist may recommend for the diagnosis of cancer:
Mammography is the most preferred test for breast cancer. A mammogram is an X-ray image of the breast. Doctors often use a mammogram to find the early signs of breast cancer. For early detection, regular mammograms are suggested.
