Managing Breast Cancer: Medications and Treatment Options

Understanding Breast Cancer

Breast Cancer is a malignant tumor that forms in the cells of the breast. It is a complex disease that affects both women and men, although it is more common in women. According to the Australian Institute of Health and Welfare, breast cancer is the second most diagnosed cancer in women in Australia.

Breast cancer occurs when abnormal cells in the breast begin to grow and multiply uncontrollably. These cells may form a lump or mass in the breast tissue, which can be detected through physical examination or screening tests such as mammography.

What is Breast Cancer?

Breast cancer is the uncontrolled growth of abnormal cells in the breast tissue. These cells may form a lump or mass, which can be felt through physical examination or detected through screening tests. Breast cancer can spread to other parts of the body through the lymphatic system or bloodstream, causing metastatic breast cancer.

Causes and Risk Factors

The causes of breast cancer are not fully understood, but there are several risk factors that increase the likelihood of developing the disease. These risk factors include:

• Genetics: Women with a family history of breast cancer are at higher risk of developing the disease.

• Age: The risk of developing breast cancer increases as women age, with most cases occurring in women over the age of 50.

• Hormones: Hormonal factors such as early onset of menstruation, late onset of menopause, and the use of hormone replacement therapy can increase the risk of breast cancer.

• Lifestyle factors: Lifestyle factors such as excessive alcohol consumption, being overweight or obese, and lack of physical activity can increase the risk of breast cancer.

Types of Breast Cancer

There are several different types of breast cancer, including:

• Ductal carcinoma in situ (DCIS): This is an early stage of breast cancer that occurs in the milk ducts of the breast.

• Invasive ductal carcinoma (IDC): This is the most common type of breast cancer, accounting for about 80% of all cases. It begins in the milk ducts of the breast and can spread to other parts of the body.

• Invasive lobular carcinoma (ILC): This type of breast cancer begins in the milk-producing glands of the breast and can spread to other parts of the body.

• Triple-negative breast cancer (TNBC): This is a less common type of breast cancer that is more difficult to treat because it does not respond to hormonal therapies.

Symptoms of Breast Cancer

The symptoms of breast cancer can include:

• A lump or mass in the breast tissue

• Changes in the size or shape of the breast

• Changes in the appearance of the nipple or breast skin

• Nipple discharge

• Swollen lymph nodes in the armpit

It is important to note that not all lumps or changes in the breast are indicative of breast cancer, and that some breast cancers may not cause any symptoms at all. Regular breast cancer screening is an important tool in detecting breast cancer early, when it is most treatable.

Diagnosing Breast Cancer

Breast cancer is a type of cancer that is usually identified through a combination of methods including screening, diagnostic tests, and staging. Early detection of breast cancer is essential as it can improve the chances of successful treatment outcomes.

Screening for Breast Cancer

Screening is the process of identifying cancer before any symptoms are apparent. Breast cancer can be detected early through regular breast cancer screening. There are two main types of breast cancer screening tests: mammograms and clinical breast exams. Mammograms use low-dose X-rays to capture images of the breast tissue. Clinical breast exams involve a healthcare professional checking the breasts for lumps or other abnormalities. It is recommended that women between the ages of 50 and 74 have a mammogram every two years.

Diagnostic Tests for Breast Cancer

If screening tests detect abnormalities, additional diagnostic tests are needed. Diagnostic tests for breast cancer include ultrasound, magnetic resonance imaging (MRI), and biopsy. Ultrasound uses high-frequency sound waves to create images of the breast tissue. MRI uses powerful magnets and radio waves to create detailed images of the breast tissue. Biopsy involves removing a small tissue sample from the breast and examining it under a microscope to check for cancer cells.

Staging of Breast Cancer

The stage of breast cancer indicates how advanced the cancer is and whether it has spread to other parts of the body. The most common system for staging breast cancer is the TNM system. TNM stands for tumor, node, and metastasis. T is for the size of the tumor, N is for the number of nearby lymph nodes that have cancer, and M is for whether the cancer has spread to other parts of the body. The stage of breast cancer helps doctors determine the best treatment plan.

In conclusion, early detection and diagnosis of breast cancer are essential to improving the chances of successful treatment outcomes. Screening tests can help detect abnormalities in breast tissue before any symptoms are apparent, while diagnostic tests, such as ultrasound, MRI, and biopsy, can help confirm a diagnosis. Staging of breast cancer helps doctors determine the best treatment plan and predict the likelihood of successful treatment outcomes.

Treating Breast Cancer

Breast Cancer treatment involves a range of options tailored to the individual based on various factors such as cancer stage, tumor size, cell type, and overall health. The treatment plan can include surgery, radiation therapy, chemotherapy, hormonal therapy, targeted therapy, or immunotherapy.

Surgery

Surgery is often the primary treatment for early-stage breast cancer. The two main types of surgical procedures for treating breast cancer include:

Lumpectomy

In a lumpectomy, the surgeon removes only the cancerous tissue and a small amount of normal surrounding breast tissue. This can be an option for women with small tumors, where preservation of the breast is possible. Lumpectomy is usually followed by radiation therapy to kill any cancer cells that may have remained.

Mastectomy

In a mastectomy, the entire breast is surgically removed, along with the nipple and areola. Mastectomy may be the preferred option for women with large tumors, multiple tumors, or cancer that has spread to the surrounding tissue.

Radiation Therapy

Radiation therapy involves the use of high-energy X-rays to kill cancer cells. It can be used as a standalone treatment, as an adjuvant to surgery, or used with chemotherapy.

External Beam Radiation Therapy

External beam radiation therapy (EBRT) involves the use of a machine placed outside the body to send radiation into the breast tissue. EBRT is usually administered in daily sessions, over several weeks.

Brachytherapy

In brachytherapy, a small radioactive implant is placed inside the breast tissue for a short period. This allows a high dose of radiation to be delivered directly to the tumor area without damaging the surrounding healthy tissue.

Chemotherapy

Chemotherapy involves the use of drugs to destroy cancer cells. It is usually administered intravenously (IV), and can also be used as an adjuvant to surgery, to shrink tumors before surgery or destroy cancer cells that may remain after surgery.

Adjuvant Chemotherapy

Adjuvant chemotherapy is administered after surgery, to kill any cancer cells that may have remained in the body.

Neoadjuvant Chemotherapy

Neoadjuvant chemotherapy is administered before surgery, to shrink the tumor and make it easier to remove.

Chemotherapy Drugs

The most common chemotherapy drugs used for breast cancer treatment include taxanes, anthracyclines, and cyclophosphamide.

Hormonal Therapy

Hormonal therapy is used to treat hormone receptor-positive breast cancer, which constitutes around 70% of all breast cancer cases. The therapy aims to block the Hormones that fuel the growth of cancer cells.

Selective Estrogen Receptor Modulators (SERMs)

SERMs are used to block estrogen from binding to the receptors on breast cancer cells, thus slowing down or stopping the growth of cancer cells.

Aromatase Inhibitors (AIs)

Aromatase inhibitors block the production of estrogen in postmenopausal women, where the ovaries no longer produce it.

Hormone Receptor Positive Breast Cancer

Hormone receptor-positive breast cancer tests positive for estrogen and/or progesterone receptors. Hormonal therapy is more effective in treating hormone receptor-positive breast cancer.

Targeted Therapy

Targeted therapy uses drugs that specifically target cancer cells, and not healthy cells. Targeted therapy can be used alone or with other treatments.

HER2-Positive Breast Cancer

HER2-positive breast cancer tests positive for a protein called Human Epidermal Growth Factor Receptor 2 (HER2), which promotes the growth of cancer cells. Targeted therapy drugs such as trastuzumab and pertuzumab block this protein to slow down or stop cancer growth.

Cyclin-Dependent Kinase 4/6 (CDK4/6) Inhibitors

CDK4/6 inhibitors block a protein that encourages cancer cells to grow, making it harder for the cancer to spread.

PARP Inhibitors

PARP inhibitors target specific enzymes that help damaged cells regenerate; cancer cells rely heavily on these enzymes to survive and grow.

Immunotherapy

Immunotherapy aims to harness the body's natural immune system to fight cancer. It is usually administered intravenously.

Immune Checkpoint Inhibitors

Immune checkpoint inhibitors work by unleashing the body's immune system to attack cancer cells. They work by blocking checkpoints that have been activated by cancer cells which prevent the immune system from attacking the cancer cells.

CAR T-Cell Therapy

CAR T-cell therapy involves modifying T cells, immune cells that fight infection and cancer, to make them better at recognizing and attacking cancer cells.

In conclusion, with advancements in cancer treatment, women with breast cancer now have several treatment options that can successfully treat the disease and improve survival rates. It is essential to discuss all the options with your doctor, understand their benefits and risks, and choose the option that suits you best.
