Understanding Cancer Treatment
Cancer treatment is designed to remove cancer cells, stop tumor growth, or prevent cancer from spreading. Treatment depends on the type of cancer, the stage of the disease, and the overall health of the patient.
Most cancer patients receive one or more types of treatment.
This guide explains how cancer is treated and the main types of cancer treatment.
This information is educational only and not medical advice.
Main Types of Cancer Treatment
Cancer treatment usually falls into two major categories:
Local Treatments
Local treatments target a specific area of the body.
Examples include:
- surgery
- radiation therapy
Systemic Treatments
Systemic treatments travel through the body.
Examples include:
- chemotherapy
- immunotherapy
- targeted therapy
- hormone therapy
Systemic treatments can reach cancer cells that have spread.
Surgery
Surgery removes cancer from the body.
Surgery is often used when cancer is localized and has not spread far.
Surgery may:
- remove tumors
- remove lymph nodes
- remove affected tissue
Early cancers are often treated successfully with surgery.
Radiation Therapy
Radiation therapy uses high-energy beams to destroy cancer cells.
Radiation damages cancer cell DNA and prevents cells from dividing.
Radiation therapy is commonly used for:
- breast cancer
- prostate cancer
- lung cancer
- skin cancer
Radiation is usually targeted to a specific area.
Chemotherapy
Chemotherapy uses drugs to destroy cancer cells.
Chemotherapy works by targeting rapidly dividing cells.
Chemotherapy may:
- shrink tumors
- slow tumor growth
- destroy cancer cells
Chemotherapy travels through the bloodstream and can reach cancer cells throughout the body.
Immunotherapy
Immunotherapy helps the immune system recognize and destroy cancer cells.
Immunotherapy may:
- activate immune cells
- improve immune detection
- strengthen immune response
Immunotherapy is used for several cancers including:
- melanoma
- lung cancer
- lymphoma
Targeted Therapy
Targeted therapy attacks specific features of cancer cells.
Targeted therapy may block:
- growth signals
- blood vessel formation
- survival pathways
Targeted therapy often affects cancer cells more than normal cells.
Hormone Therapy
Some cancers depend on hormones to grow.
Hormone therapy blocks hormone signals.
Hormone therapy is commonly used for:
- breast cancer
- prostate cancer
Blocking hormones can slow tumor growth.
Combination Treatments
Many patients receive multiple treatments.
Common combinations include:
- surgery + chemotherapy
- surgery + radiation
- chemotherapy + immunotherapy
Combination treatment often improves outcomes.
Treatment Goals
Cancer treatment goals include:
Cure
Treatment removes all cancer.
Control
Treatment slows cancer growth.
Symptom Relief
Treatment reduces symptoms.
Side Effects of Treatment
Cancer treatments affect normal cells as well as cancer cells.
Common side effects include:
- fatigue
- nausea
- hair loss
- appetite changes
Side effects vary by treatment type.
Personalized Treatment
Modern cancer treatment is personalized.
Doctors consider:
- cancer type
- stage
- genetics
- patient health
Treatment plans are individualized.
How Treatment Is Chosen
Doctors choose treatment based on:
- cancer stage
- tumor location
- spread of cancer
- patient health
