Hormonal Therapy to Treat Breast Cancer
Breast cancer is a type of cancer that occurs when the cells in a person's breast start growing uncontrollably.
Hormonal therapy, also known as endocrine therapy, is a primary treatment for women with hormone receptor-positive breast cancer. It is used to prevent the growth, spread, or recurrence of breast cancer. Hormonal therapy works by blocking or removing hormones like estrogen and progesterone from the body. This prevents these hormones from reaching cancer cells and stimulating their growth.
Here are some key points about hormonal therapy and its use in treating breast cancer:
- Hormonal therapy acts as the opposite of hormone replacement therapy. Its goal is to lower the levels or effects of estrogen and progesterone in the body.
- Hormonal therapy interrupts the influence of hormones on the growth and functioning of cancer cells.
- By blocking or removing hormones, hormonal therapy makes it less likely for cancer cells to survive.
- Hormonal therapy also prevents healthy breast cells from receiving hormones that could stimulate the regrowth of cancerous cells.
- A pathology test on a tumor tissue sample can determine if the cancer has estrogen and progesterone receptors. If it does, it is called estrogen-receptor positive or progesterone-receptor positive.
- Hormonal therapy for breast cancer includes anti-estrogen durgs that blocks estrogen receptors in tumors, preventing their growth.
- Hormonal therapy is often used in combination with other treatments like surgery, chemotherapy or radiation therapy.
- It is primarily used to treat women over 50 but may also be used for low-risk postmenopausal women.
Hormonal therapy offers several advantages for breast cancer treatment. It provides an attractive therapeutic option due to its convenience of oral administration and generally tolerable safety profile compared to chemotherapy and other targeted therapies. Additionally, research has shown that hormonal therapy can effectively prevent or delay the recurrence of cancer after other treatments have removed the primary tumor.
It's important to note that while hormonal therapy can be effective in treating breast cancer, it may also have some adverse effects such as changes in bodyweight, menstrual cycle alterations, and a small risk of uterine cancer. However, these side effects can be managed with proper medical supervision.
Overall, hormonal therapy plays a crucial role in treating hormone receptor-positive metastatic breast cancers by blocking or removing hormones that fuel the growth of cancer cells.
Hormonal therapy, also known as endocrine therapy, is a primary treatment for hormone receptor-positive metastatic breast cancer. It works by blocking or lowering the levels of estrogen and progesterone in the body. This is important because hormone receptor-positive breast cancer cells rely on these hormones to grow and survive.
Here's how hormonal therapy works in treating breast cancer:
- Hormonal therapy acts like the opposite of hormone replacement therapy (HRT): Hormonal therapy is sometimes referred to as anti-hormone treatment because it works against the effects of hormones on cancer cells. It aims to interrupt the influence of hormones on the growth and functioning of cells.
- There are different types of hormonal therapy for breast cancer. They may:
- Block estrogen from connecting to cancer cells.
- Suppress the ovaries from producing estrogen.
- Suppress other parts of the body, such as body fat, from making estrogen.
- Blocking estrogen and progesterone: By lowering the levels of estrogen and progesterone in the body, hormonal therapy prevents these hormones from reaching cancer cells. This deprives the cancer cells of the estrogen they need to grow and survive.
- Inhibiting cancer cell survival: When hormones are blocked or removed, hormone receptor-positive cancer cells are less likely to survive. This helps slow down or stop the growth of breast cancer.
- Preventing regrowth: Hormonal therapy also stops healthy breast cells from receiving hormones that could stimulate the regrowth of cancerous cells within the breast or elsewhere in the body.
Hormonal therapy is considered a systemic treatment because it targets hormones throughout the body, rather than specific areas like surgery or radiation therapy. It can be used as a standalone treatment or in combination with other therapies, depending on individual circumstances.
It's important to note that hormonal therapy should not be confused with menopausal hormone therapy (MHT), which is used to relieve menopause symptoms. Hormonal therapy for breast cancer blocks the growth of hormone receptor-positive breast cancer, while MHT can stimulate its growth.
Hormonal therapy is a treatment option for certain types of cancer, such as breast and prostate cancer. It involves using hormones or medications that interfere with hormone function to slow down or stop the growth of cancer cells. Here's how hormonal therapy is used and some precautions and potential side effects to be aware of:
How to use or take hormonal therapy:
- Before starting hormonal therapy, a sample of the tumor may be sent to a special lab to determine if this type of treatment is likely to be effective.
- Hormones can be administered orally (by mouth), intravenously (through a vein), or intramuscularly (into a muscle).
Precautions and potential side effects of hormonal therapy:
- It's important to note that hormonal therapy is not suitable for all types of breast cancer.
- Side effects from the anti-estrogen effects of hormone therapy include hot flashes, vaginal dryness, and changes in menstrual cycles.
- Other side effects may occur and may differ based upon the specific hormone therapy used. Examples include:
- Blood clots, such as deep vein thrombosis (DVT) or pulmonary embolus (PE) are an uncommon but serious side effect. Symptoms include pain, redness or swelling in the calf or shortness of breath and chest pain. Call the doctor immediately if these symptoms occur while on hormonal therapy.
- Muscle, join, or bone pain.
- Eye problems, such as cataracts.
- Always consult with a healthcare professional for personalized advice.
It's important to remember that these are general precautions and potential side effects associated with hormonal therapy. Every individual is unique and it's important to consult with your doctor before starting any treatment or medication. They will be able to provide personalized advice based on your specific situation and needs.
Medication dosing may be affected by many factors. Check with your health care professional about dosing for your individual situation. Other side effects can occur. Check with your health care professional or read the information provided with your medication for additional side effect information.
