Medical Oncology

Medical Oncology involves cancer treatment through chemotherapy, immunotherapy, targeted therapy, and hormone therapy. Medical oncology is a type of systemic therapy that oncologists use to destroy visible tumors as well as those that cannot be seen through imaging. Some patients require medical oncology along with radiation therapy and surgical oncology for cancer treatment.

Medical oncology treatment can alone treat cancer or be used along with other types of cancer treatment like radiation oncology and surgery. A medical oncologist provides personal assessment and plans the treatment according to the type & staging of cancer. Prompt cancer treatment helps to manage the symptoms of cancer and side effects that one might otherwise experience.


Targeted therapy
Hormone therapy

In medical oncology, chemotherapy is used to treat cancer. A biological agent or hormone or chemical travels into the bloodstream to act on the cancerous cells and kill them. The success rate of chemotherapy is pretty high and has been used for many years in cancer treatment.

There are some chemotherapeutic agents, too, that destroy the rapidly dividing cancerous cells for cancer treatment. These agents interfere with the growth of cancer cells to damage them permanently and prevent their further progression. This helps in shrinking tumors and curing cancer by preventing it from multiplying. Furthermore, the patients get relief and live longer than expected.


A cancer patient who cannot benefit much from chemotherapy or cannot tolerate the same opts for immunotherapy. This treatment involves strengthening the natural defense system of the body to resist the attack of cancer cells. It activates the immune system and prevents the growth of cancer cells to stop them from spreading

The therapy alters the immune response of the body to fight cancerous cells. They target cancer cells either by cytokines, cancer vaccines, monoclonal antibodies, checkpoint inhibitors, or immunomodulators. This therapy can be used alone or along with other types of treatment for cancer.

Targeted therapy

In this therapy, the biological agent targets a particular protein or gene found in the cancer cells. This helps in stopping cell proliferation and hence, this cutting-edge cancer treatment is pretty much effective in several types of cancers. Targeted therapy is given through oral medications or IV infusion in conjunction with some other type of medical oncology treatment.

Targeted therapy reduces cancer growth and is given before or after the surgery to kill cancerous cells or shrink the tumor size in advanced stages of cancer. As it acts specifically on cancer cells, it has mini side effects like diarrhea. The medications used in this therapy ensure the prevention of cancer cell growth by targeting different cellular pathways.

Hormone therapy

Hormones have a role in the treatment of cancer, and hormone therapy may alter cancer growth. Hormonal treatment slows down hormone production in the patient's body to stop the growth and development of cancerous cells. This therapy blocks cancer cell receptors, such as in, prostate cancer and breast cancer to work at their best. It lowers the hormonal levels in the body- testosterone in men and estrogen in women.

Hormone therapy does not allow the continued growth of cancer and is usually given as an oral medication for a certain time. The doctor might also administer this therapy through injection.
