FAQ's Related to Medical Oncologist

What does a radiation oncology doctor do?

Radiation oncologists are medical doctors who specialise in treating cancer using radiation therapy. They plan and oversee radiation treatments, ensuring that cancer cells are targeted while minimising damage to surrounding healthy tissue.

What types of cancers do radiation oncologists treat?

Radiation oncologists treat a wide range of cancers, including but not limited to:

  • Breast cancer
  • Prostate cancer
  • Lung cancer
  • Head and neck cancers
  • Brain tumors
  • Gastrointestinal cancers
  • Gynecological cancers
  • Lymphomas and more
What is radiation therapy, and how does it work?

Radiation therapy uses high-energy rays (such as X-rays, proton beams, or electrons) to destroy or damage cancer cells. It works by damaging the DNA of cancer cells, preventing them from growing or dividing.

Is radiation therapy painful?

Radiation therapy itself is painless, much like getting an X-ray. However, some side effects (like skin irritation or fatigue) may develop depending on the treated area.

How long does radiation treatment usually last?

Treatment duration varies based on the type and stage of cancer. It can range from a single session (in stereotactic radiotherapy) to daily treatments over several weeks.
