Breast cancer

What Is Breast Cancer?

Breast cancer is a type of tumor that develops when breast cells begin to grow abnormally and uncontrollably. These cells usually divide faster than healthy cells, accumulating to form a lump or tumor. This growth most often starts in the milk ducts or the lobules that produce milk, and it may spread to other parts of the body if not detected and treated early.

What Are the Early Symptoms of Breast Cancer?

In its early stages, breast cancer may be completely silent. However, there are signs you may notice if you are attentive. The most common is a hard, painless lump felt in the breast or under the armpit. You may also notice slight changes in the size or shape of the breast, or a feeling of heaviness or unusual tightness in a specific area—signs that warrant medical follow-up without delay or excessive worry.

What Are the Signs of Advanced Breast Cancer?

As the disease progresses, symptoms become more noticeable and may affect the skin and surrounding tissues. You may notice changes in the breast skin resembling an orange peel or inward retraction of the nipple.

Skin ulcers, bloody nipple discharge, and persistent pain in the breast or back may also appear, indicating that the tumor may be affecting a larger area of tissue.

What Causes Breast Cancer?

Breast cancer does not have one single cause; rather, it results from a combination of genetic, environmental, and lifestyle factors.

In some cases, genetic mutations play a major role, while in others, hormonal or health-related factors influence breast cells over time.

Key risk factors include:

1. Previous radiation therapy to the head, chest, or neck
2. Advancing age, especially over 55 years
3. A family history of breast cancer in first-degree relatives
4. Being female, as women are more commonly affected than men
5. Inherited or acquired genetic mutations, particularly BRCA1 and BRCA2
6. Smoking and alcohol consumption
7. Overweight and obesity
8. Not having children or having children later in life
9. Long-term use of hormonal therapies
10. Early puberty or late menopause

What Are the Stages of Breast Cancer?

Breast cancer develops and progresses through several stages:

1. Stage 0: Cancer cells are confined to the breast with no spread to lymph nodes.
2. Stage I: Tumor size is 2 cm or less and confined to the breast.
3. Stage II: Cancer may spread to underarm lymph nodes without size increase, or the tumor grows to 2–5 cm but remains within the breast.
4. Stage III: Tumor exceeds 5 cm without spreading, or measures 2–5 cm with spread to underarm lymph nodes.
5. Stage IV: Tumor grows beyond 5 cm with spread to lymph nodes near the chest bones, or lymph nodes become attached to surrounding tissues.
6. Stage V: Cancer spreads to the chest wall or skin.
7. Stage VI: Wider spread with involvement of more lymph nodes.
8. Stage VII (Final): Cancer spreads invasively to distant organs such as the brain, liver, lungs, or bones.

How Is Breast Cancer Diagnosed?

Diagnosis begins with a clinical examination of the breast and underarm area to detect lumps or abnormal changes, followed by a review of medical history and necessary tests for accuracy.

Diagnostic tests include:

Mammogram: The most important tool for early detection, identifying small lumps or calcifications not felt manually.

Ultrasound and MRI: Ultrasound distinguishes solid masses from fluid-filled cysts, while MRI is used in special cases to provide highly detailed images.

Breast Biopsy: A tissue sample is taken when a tumor is suspected to determine the nature and type of cells and guide treatment decisions.

What Is the Treatment for Breast Cancer?

Treatment varies based on tumor type and stage and often involves a combination of methods aimed at eliminating cancer cells while preserving body function and appearance.

Breast Cancer Surgery

Surgery is the cornerstone of treatment, ranging from tumor removal with a margin of healthy tissue (breast-conserving surgery) to full mastectomy in some cases. Lymph nodes under the arm may also be examined, and reconstructive surgery is often performed afterward.

Radiation Therapy

High-energy rays are used to destroy remaining cancer cells after surgery. It is a localized treatment that significantly reduces the risk of recurrence.

Chemotherapy

Chemotherapy uses powerful drugs that travel through the bloodstream to target cancer cells anywhere in the body. It may be used before surgery to shrink tumors or after surgery to prevent spread. Modern supportive medications have reduced side effects considerably.

Hormonal Therapy

Some breast cancers grow in response to hormones like estrogen. Hormonal therapy blocks hormone receptors or reduces hormone production and is often taken as long-term oral medication to prevent recurrence.

Other Treatment Options Include:

Targeted Therapy: Focuses on specific molecules involved in cancer growth.

Immunotherapy: Strengthens the immune system to recognize and fight cancer cells.

What Is the Survival Rate for Breast Cancer?

Medical research shows a significant improvement in breast cancer survival rates, especially when detected early, with cure rates exceeding 90%. This reflects major advances in diagnostic tools and treatment options, confirming that breast cancer is no longer a dead end but a condition that can often be overcome.

What Are the Complications of Breast Cancer?

Complications may arise from disease progression or treatment side effects. One common complication is lymphedema in the arm due to affected lymph nodes, causing swelling or heaviness.

Persistent fatigue is also common during treatment. In advanced cases, cancer may spread to bones or vital organs, requiring close medical follow-up to maintain quality of life and reduce pain.

How Can Breast Cancer Be Prevented?

Prevention starts with simple lifestyle steps, such as:

1. Maintaining a healthy weight and reducing processed and high-fat foods
2. Engaging in regular physical activity, such as walking
3. Recognizing the protective role of breastfeeding

Most importantly, regular breast screening remains the strongest safeguard for detecting changes early before they progress.

Conclusion

Awareness and early detection remain the foundation of breast cancer prevention and control. Regular medical follow-up and a healthy lifestyle reduce risks and increase recovery chances, especially with continuous advances in diagnosis and treatment.
