Breast Cancer: Causes, Diagnosis, Treatment

Breast cancer is the most common cancer in women. It happens when breast cells start growing out of control. There are different types of breast cancer and many treatment options. Several physical symptoms can show up indicating breast cancer's presence and growth.

This article will cover what causes breast cancer, early signs for diagnosis, risk factors, and available treatment options.

Causes of Breast Cancer

Breast cancer happens when breast cells divide and multiply abnormally to form lumps or tumors. Experts don't know the exact cause in every case, but some factors increase the chance of getting breast cancer. These can include:-

• Being female. Women are more likely to get breast cancer than men.

• Genetic genes. Some gene mutations can be passed from parents to children, increasing breast cancer risk.

• Age, the risk of breast cancer goes up as you get older.

• Reproductive history, women having their first child after 30, or those who never got pregnant, have higher chances of breast cancer.

• Personal or family medical history, having family members with breast cancer like mom or sister.

• Lack of physical activity, andobesityare all factors that increase the chance of breast cancer.

• Exposure to hormone therapy or radiation treatment raises breast cancer risk.

• Drinking alcohol.

Types of Breast Cancer

Breast cancer types can be classified based on the breast tissue where the tumor starts, like Lobular cancers and Ductal cancers. Some types of breast cancer include:

1. Metastatic Breast Cancer

Metastatic breast cancer, also called stage 4 or advanced breast cancer, means the cancer has spread beyond the breast to other parts of the body, usually the brain or liver.

Though metastatic breast cancer can't be cured, it can be treated with chemo, other systemic therapies, sometimes surgery, or radiation.

2. Triple-Negative Breast Cancer

Triple-negative breast cancer (TNBC) makes up about 10% to 15% of all breast cancers. This type lacks three receptors, which are estrogen hormone Andthe hormone progesterone and the HER2 protein. These receptors usually help breast cancer grow, that's why it's called triple-negative breast cancer.

This type of breast cancer can grow and spread faster and treatment options are limited.

3. Inflammatory breast cancer

Inflammatory breast cancer is a rare aggressive type, making up about 1% to 5% of breast cancer cases.

It develops fast as cancer cells block lymph vessels in the breast skin, causing swelling, redness, and inflammation. Diagnosing it is often hard because there are no lumps. It can be treated with chemo, radiation, and surgery.

Breast cancer symptoms

One of the most common symptoms of breast cancer is having lumps or a tumor in the breast area, Other symptoms may include:-

• Lumps or swelling.

• Skin dimpling or puckering.

• Pain and inflammation.

• Changes in breast size.

• Changes in the skin of the breast or nipple.

• The nipple turning inward.

• Swelling of lymph nodes.

Also, there are some early signs, which are minor changes in the breast, including:-

• Changes in the shape, feel, or size of the breast.

• Changes in the shape, feel, or size of the nipple.

• Unusual discharge from the nipple.

Breast cancer often can't be caught early, but it can be found with regular checkups and mammograms.

How breast cancer is diagnosed

There are many ways to diagnose breast cancer, and one of the main methods is Breast self-examMany people find it useful to keep track of breast health by checking the shape and look of the breast for any issues or changes. You can do this by following these steps:

• Look at both breasts for any changes in size, shape, contour, or color.

• Check the nipples for any new holes, boils, lumps, fluids, or discharge.

• Use touch to feel for any change in texture or size of the breast.

There are other tests, like mammograms which use X-rays or MRIsand finding abnormal results on these tests is often one of the first steps in diagnosing breast cancer.

Also, the healthcare provider may ask to take a small sample of breast tissue to check for cancer cells, called a biopsy.

Many breast lumps can be normal and non-cancerous. Experts say that hard, painless lumps with irregular shape are more likely to be cancerous. But some cancer lumps can be round, soft, smooth, and painful. So, don’t ignore any lumps in the breast.

Breast Cancer Stages

Breast cancer stages show how far the cancer has spread in the body. This helps the healthcare provider judge how serious it is and plan the best treatment. The breast cancer stages include:

1. Stage 0

Stage 0 breast cancer is the earliest stage. This means some cells look abnormal but haven’t turned into cancer yet. Or they’re cancer cells in place only and haven’t spread to other parts of the body. Patients at this stage usually have better chances of treatment.

2. Stage One

Stage one breast cancer means the cancer has grown into nearby breast tissues or has just started spreading a bit to nearby lymph nodes, or hasn't reached lymph nodes yet.

3. Stage Two

Stage two breast cancer means the tumor has grown bigger, up to 2 cm, or it might have spread to more lymph nodes under the arm.

4. Stage Three

Stage three breast cancer means it has spread more than stage two but hasn't reached organs or tissues around the breast area yet. This stage includes most inflammatory breast cancers.

5. Stage Four

Stage four breast cancer means the cancer has spread to other parts or organs of the body, like the brain, liver, bones, skin, and lungs. This includes metastatic breast cancer.

Breast Cancer Treatments

There are many treatment options for breast cancer, suggested by the healthcare provider based on the patient's condition and the stage of the cancer. Some treatment plans might combine several treatments together, which can include:-

• Surgery

Depending on the specific breast cancer case, there are two surgeries you might have. The first is tumor removal surgery where the cancerous tumor and some surrounding tissue are removed from the breast.

The second is mastectomy, which is the full removal of one or both breasts. This can be used to treat breast cancer or prevent it.

• Chemotherapy

Chemotherapy is a common treatment option for many breast cancer cases. It can be given by injection, intravenously, or as pills.

Chemo drugs stop cancer cells from growing fast.

• Radiation therapy

Radiation therapy uses high-energy rays to target and destroy cancer cells. It's often used after tumor removal or mastectomy, and if cancer spreads to other parts of the body.

• Hormone therapy

Some breast cancers respond to hormone therapy, which includes drugs that block production or action of estrogen and progesterone.

Sometimes hormone therapy is used before or after surgery to help make surgery more successful or lower chances of cancer returning.

• Other treatments

Other drugs can treat certain breast cancer types. Immunotherapy can boost your immune system to fight cancer cells. PARP inhibitor drugs often treat breast cancer with BRCA1 and BRCA2 gene mutations.

Breast cancer in men

Even though breast cancer in men is rare, it can happen. Men can get breast cancer at any age, but older men are more at risk. Some symptoms of breast cancer in men include:

• Thickening of breast tissue.

• A painless lump in the breast.

• Discharge from the nipples.

• Changes in the breast like lumps, redness, or peeling.

• Changes in the nipple like redness, peeling, or it turning inward.

In the end, early detection of breast cancer is a big step toward successful treatment and preventing the tumor from spreading to other parts of the body. So, it's important to watch carefully for any changes in the breast or nipple. Regular checkups like mammograms should be done continuously as recommended.
