Breast Cancer: What Every African Woman Should Know

Introduction

Breast cancer is the most common cancer in women everywhere on earth, and in Africa it kills a higher share of the women it touches than almost anywhere else. Not because the disease is worse here, but because it is found later. A lump checked within weeks is usually curable; the same lump ignored for a year often is not.

This short guide is for every woman in Africa, and for the people who love her.

The numbers, worldwide and in Africa

In 2024, according to the International Agency for Research on Cancer (GLOBOCAN) [1]:

• 2.4 million women worldwide were diagnosed with breast cancer, and 694,000 died: one in every four cancers in women.
• 225,643 of those diagnoses were in Africa, where breast cancer makes up 32% of all cancers in women, and about 100,000 African women died.

The gap is in survival. In the world's wealthiest countries, 17 of every 100 women diagnosed die of the disease; in the poorest, 56 do [2]. And African women are younger: nearly half of Africa's cases are in women under 50, against fewer than one in five in Europe and North America [2]. Hospital studies across the continent find that seven in ten women arrive with stage III or IV disease [3], when treatment is harder, costlier and less likely to cure.

By 2050 the world will see 3.2 million cases and 1.1 million deaths a year, with the sharpest rises in Africa [2].

Why so late?

Not because women don't notice. Studies from Nigeria to Tanzania give the same reasons: a lump that didn't hurt, so it didn't seem serious; fear; the cost of scans and surgery; distance to a hospital; a first stop at a herbalist or prayer house; and the belief that cancer is always fatal. Two facts undo every one of these delays: a painless lump is the most common first sign, and early breast cancer is highly curable.

The signs to act on

Most breast changes are not cancer, but each of these needs a clinic visit within two weeks:

• A new lump or thickening in the breast or armpit, especially if painless
• A change in the size or shape of one breast
• Dimpling, puckering or an "orange peel" look of the skin
• A nipple that has turned inward, or a rash, crust or sore on it
• Discharge from the nipple, especially if bloody
• Redness, warmth or swelling that does not settle, or a breast that feels different from the other

Pain alone is rarely cancer; pain with any sign above should be checked.

Six changes that need a clinic visit within two weeks. A painless lump is the most common first sign.

How to check yourself

Once a month, a few days after your period (or a fixed date after menopause):

1. Look in a mirror, arms down, then raised, then hands on hips: any change in shape, skin or nipple?
2. Feel each breast with the flat pads of three fingers in small circles, collarbone to below the breast, armpit to breastbone, lightly then firmly.
3. Check the armpits, and gently squeeze each nipple for discharge.

Self-examination teaches you what is normal for you, so you notice change. Add a clinical breast examination by a nurse or doctor every one to three years from your twenties, yearly from 40, and mammography where available from 40 to 50 onward; ask your nearest teaching hospital what your country offers.

Look, feel, check: a monthly self-examination takes five minutes.

If something is found

A lump is checked with an ultrasound (available in most district hospitals) or mammogram, then if needed a needle biopsy, the only way to confirm cancer. Keep your results. Early cancer is usually treated with surgery (often keeping the breast), plus radiotherapy, hormone tablets or chemotherapy depending on the type. Many national schemes now cover part of the cost (Nigeria's Cancer Health Fund, Ghana's NHIS, Kenya's SHA, Rwanda's Mutuelle); ask the hospital's social welfare unit.

Lower your risk

Breastfeed if you can; keep a healthy weight; move for 150 minutes a week; limit alcohol; do not smoke. If your mother, sister or daughter had breast or ovarian cancer, tell your doctor: you may need checks from an earlier age.

Key takeaways

• Breast cancer is the commonest cancer in women worldwide; in Africa it is found late and kills younger women.
• A painless lump is the most common first sign. Pain is not required.
• Check yourself monthly; get any change seen within two weeks.
• Found early, breast cancer is usually curable. Do not wait, and do not go to a herbalist first.
• Help exists for the cost. Ask the hospital.
