Targeted therapy is a type of cancer treatment that focuses on specific molecules or proteins that are
involved in the growth and spread of cancer cells. Unlike traditional chemotherapy, which can affect
both healthy and cancerous cells, targeted therapy is designed to be more precise and minimize harm to
healthy cells.
Targeted therapy drugs work by blocking or interfering with specific molecules or pathways that are
involved in cancer cell growth and survival. For example, some drugs target proteins on the surface of
cancer cells that allow them to divide and grow uncontrollably. Other drugs target specific signaling
pathways within cells that are involved in cancer growth and progression.
Targeted therapy is used to treat many different types of cancer, including breast cancer, lung cancer,
colorectal cancer, and melanoma, among others. It may be used alone or in combination with other
treatments, such as chemotherapy or radiation therapy.
One advantage of targeted therapy is that it can often cause fewer side effects than traditional
chemotherapy, because it specifically targets cancer cells without harming healthy cells. However,
targeted therapy can still cause side effects, which can vary depending on the specific drug being used
and the individual patient.
Some common side effects of targeted therapy may include fatigue, nausea, diarrhea, skin rash, and
changes in blood pressure or heart rate. Patients should always discuss any side effects with their
doctor, who can help manage symptoms and adjust treatment as needed.
Targeted therapy is typically administered through intravenous infusion or oral medication. Patients may
receive targeted therapy in a hospital or clinic setting, or they may be able to take their medication
at home.
It's important to note that targeted therapy is not a cure for cancer, and it may not be effective for
every patient or every type of cancer. However, it can be an important tool in the fight against cancer,
providing patients with more treatment options and helping to improve outcomes for many people with
cancer.
