How does medical oncology work?

Medical oncology is the practice of using medications to kill cancer cells that are rapidly multiplying. Chemotherapy can help reduce cancer cell growth and prevent it from spreading to other places of the body. It may be combined with radiation to aid in tumor shrinkage prior to surgery.

Can a medical oncologist perform surgery?

Biopsies and surgery to remove malignant growths are the most common procedures performed by surgical oncologists. They can also undertake surgery to detect the stage of cancer and how far it has spread. Surgical oncologists may also undertake prophylactic procedures in some cases.

What is the motive of neo adjuvant treatment?

The goal of neoadjuvant therapy is to reduce the tumour burden, which may allow more patients to have potentially curative surgery, and to reduce the risk of recurrence.

When is neoadjuvant therapy used?

Neoadjuvant therapy is the treatment of tumours with chemotherapy, radiation therapy, and endocrine therapy before they are removed from the body. In the beginning, it was used because it helped with surgery, downgrading tumours, and allowing breast-conserving surgery instead of mastectomy.

Why is induction therapy used?

Therapy for induction is the first part of the process. There is a goal for induction therapy: to get rid of as many cancer cells as possible so that the body can go into remission. Most of the time, when you start treatment, you'll need to stay in the hospital for a few weeks. Everything that was there is gone.
