Chemotherapy is a cancer treatment that uses drugs to kill cancer cells. It's a systemic treatment, meaning it affects the entire body, not just the area where the cancer is located. These drugs can target rapidly dividing cells, including cancer cells, but they can also affect other fast-growing cells in the body, leading to side effects.

How it works:
Chemotherapy drugs are designed to interfere with the cell cycle, the process by which cells grow and divide.

They can do this by stopping cells from replicating their DNA, preventing them from dividing, or causing them to die.

Because cancer cells divide more rapidly than normal cells, chemotherapy is particularly effective at targeting them.

How it's given:
Chemotherapy can be administered in various ways, including orally (as pills), intravenously (through a vein), or by injection.

It can also be given as an infusion, directly into the spinal fluid, or even topically.

Why it's used:
Cure cancer:
In some cases, chemotherapy can eliminate all cancer cells and cure the disease.

Reduce the risk of recurrence:
Chemotherapy can be used to kill any remaining cancer cells after other treatments, like surgery or radiation therapy, to reduce the chance of the cancer returning.

Shrink tumors:
Chemotherapy can shrink tumors, making them easier to remove surgically or improving the effectiveness of radiation therapy.

Relieve symptoms:
Chemotherapy can shrink tumors that are causing pain or other symptoms, improving the quality of life for patients.

Side effects:
Chemotherapy can cause a range of side effects, as it affects rapidly dividing cells in the body, including:
Mouth sores
Nausea and vomiting
Hair loss
Fatigue
Changes in appetite
Bone marrow suppression, leading to a decrease in blood cell counts

Important notes:
The specific drugs and dosages used in chemotherapy vary depending on the type and stage of cancer, as well as the individual patient's needs and health.
Chemotherapy is often given in cycles, with periods of rest between treatments to allow the body to recover.
Side effects can vary from person to person and can often be managed with medication and supportive care
