Breast cancer is one of the most important health conditions to understand because it affects millions of people worldwide. In places like Ghana, many cases are diagnosed late, not because detection is difficult, but because awareness is low. Knowing what to look for and acting early can make the difference between simple treatment and life-threatening disease.
What is Breast Cancer?
Breast cancer develops when cells in the breast grow uncontrollably. These abnormal cells often begin in the milk ducts, called ductal carcinoma, or in the milk-producing glands, called lobular carcinoma.
Under normal conditions, the immune system identifies and destroys abnormal cells. In cancer, however, these cells multiply faster than the body can control. This leads to the formation of a lump or tumor. Some cancers can spread to nearby lymph nodes and then to distant organs such as the lungs, liver, or bones.
The most important factor is timing. When detected early, breast cancer is highly treatable and survival rates are very high.
Ama, a 42-year-old teacher in Accra, discovers a small lump during a routine bath. She immediately visits a clinic, where the cancer is detected at an early stage. After treatment, she returns to her normal life within months. Early action made the difference.
Warning Signs to Know
You should seek medical attention if you notice any of the following:
- A new lump or thickening in the breast or armpit
- A change in breast size or shape
- Skin dimpling or puckering that looks like orange peel
- A nipple that suddenly turns inward
- Discharge from the nipple, especially if bloody or from one side
- Redness, rash, or persistent itching of the breast
- Persistent pain in one area of the breast
Most of these symptoms are not caused by cancer, but only proper medical evaluation can confirm that.
Esi, aged 38, notices a painless lump near her armpit but ignores it because it does not hurt. Six months later, the lump has grown and the cancer has spread to nearby lymph nodes. If she had gone earlier, treatment would have been simpler and more effective.
Who is at Risk?
Non-Modifiable Risk Factors
Some risk factors cannot be changed:
- Being female, although men can also develop breast cancer
- Increasing age, especially after 40
- Family history of breast cancer
- Genetic mutations such as BRCA1 and BRCA2
- Early menstruation or late menopause
- Dense breast tissue
These factors increase risk but do not guarantee disease.
Adjoa has no unhealthy habits but has a strong family history of breast cancer. Because she understands her risk, she attends regular screenings, which helps ensure early detection if cancer develops.
Modifiable Risk Factors
Some lifestyle factors can influence risk:
- Alcohol consumption
- Physical inactivity
- Obesity after menopause
- Long-term hormone replacement therapy
- Not breastfeeding
- Smoking
Making healthier lifestyle choices can reduce overall risk.
Mary reduces her alcohol intake, starts regular exercise, and maintains a healthy weight. While this does not eliminate her risk completely, it significantly lowers her chances of developing breast cancer.
How is Breast Cancer Diagnosed?
If a breast abnormality is found, doctors may use several tests:
- Mammogram, which is an X-ray of the breast
- Ultrasound, especially useful in younger women
- MRI, often used for high-risk individuals
- Biopsy, where a small tissue sample is examined
A biopsy confirms the diagnosis and provides information about the type of cancer and how it behaves.
After noticing a lump, Linda undergoes a mammogram and ultrasound. A biopsy confirms early-stage cancer. Because of early diagnosis, her treatment plan is straightforward and effective.
Treatment Options
Surgery
Surgery is often the first step in treatment.
- Lumpectomy removes the tumor and a small surrounding area
- Mastectomy removes the entire breast
The choice depends on the size and location of the tumor, as well as patient preference.
A patient with a small tumor chooses a lumpectomy followed by radiation. She preserves her breast and achieves a good outcome.
Radiation Therapy
Radiation uses high-energy rays to destroy remaining cancer cells after surgery. It reduces the risk of cancer returning in the same area.
After surgery, a patient undergoes daily radiation sessions for several weeks. This lowers her risk of recurrence significantly.
Chemotherapy
Chemotherapy uses drugs to destroy rapidly dividing cells. It may be used before or after surgery depending on the stage of the cancer.
A patient with a larger tumor receives chemotherapy before surgery, which shrinks the tumor and allows for less extensive surgery.
Hormone Therapy
Some breast cancers depend on hormones like estrogen to grow. Drugs such as tamoxifen block these hormones and reduce recurrence risk.
A woman with hormone receptor-positive cancer takes tamoxifen for several years after treatment. This significantly lowers the chance of the cancer returning.
Targeted Therapy
Some cancers overexpress a protein called HER2. Targeted drugs such as trastuzumab specifically attack these cancer cells with fewer side effects than traditional chemotherapy.
A patient diagnosed with HER2-positive cancer receives targeted therapy alongside chemotherapy. Her treatment becomes more precise and effective.
Self-Examination: Do This Monthly
Check your breasts a few days after your period ends:
- Look for visible changes in shape, size, or skin
- Raise your arms and observe again
- Use the flat of your fingers to feel the entire breast, including the armpit
- Check both standing and lying down
- Gently squeeze the nipple for discharge
If you are unsure about anything you feel, consult a healthcare provider.
Efua makes it a habit to check her breasts monthly. One month, she notices a slight change and seeks medical advice early. The issue is addressed before it becomes serious.
Breast Cancer in Men
Men also have breast tissue and can develop breast cancer, although it is rare. It accounts for about 1% of all breast cancer cases.
Not every lump in a manβs chest is cancer. Many are caused by non-cancerous conditions such as gynecomastia, which is a benign enlargement of breast tissue often linked to hormonal changes, medications, or weight gain.
However, certain features make a lump more concerning:
- A hard, painless lump, especially directly behind the nipple
- A lump that does not move easily
- Nipple discharge, particularly if bloody
- Skin changes such as dimpling, ulceration, or redness
- Nipple retraction
Because male breast cancer is unexpected, men often ignore early signs, which can delay diagnosis.
Kwame notices a small swelling in his chest and assumes it is due to weight gain. Over time, the lump becomes firmer and the skin around his nipple starts to change. When he finally visits a doctor, tests are done to rule out cancer. The key lesson is not that every lump is cancer, but that any persistent or unusual change should be checked early.
Final Thoughts
Breast cancer is not a death sentence, especially when detected early. Awareness, regular self-examination, and timely medical care can save lives. Do not ignore changes in your body. Acting early gives you the best chance of successful treatment and recovery.
