Medical Oncology

Cancer is the disordered growth of cells. When it reproduces in an organ different from the one that originates it is known as metastasis.

Many people are now cured of cancer after receiving treatment. The choice of one or more treatments depends on several reasons: the type of tumor, the site of the tumor, its size and whether or not it has invaded other organs.

Your doctor will tell you about the treatments that have been chosen in your particular case.


There are three major specialties for the treatment of cancer:

1. Oncology Surgery Is the removal of all or part of the malignant tissue. It is used as a diagnosis by biopsy or as a treatment.
2. Medical Oncology and Hematology: Treat cancer with medications.
3. Radiotherapy: Is the treatment of tumors with radiation.

Chemotherapy is a type of cancer treatment, which uses drugs or drugs to kill cancer cells. These drugs can be given as follows:
Oral: tablets or capsules to take.
