8 Warning Signs of Breast Cancer You Should Never Ignore
Breast cancer affects millions of people worldwide, but catching it early can make all the difference. While many breast changes are benign, it’s essential to know the warning signs that could indicate breast cancer. Here are eight signs to watch out for, so you can be proactive about your health.
1. A New Lump or Mass in the Breast or Armpit
A lump is the most common sign of breast cancer, but not all lumps are dangerous. Cancerous lumps are often hard, painless, and have irregular edges. However, some can be soft and tender. Whether the lump is in your breast or armpit, it’s critical to get it checked out by a healthcare professional.
2. Changes in Breast Size or Shape
Notice one breast suddenly looking different than the other? Significant or sudden changes in breast size, shape, or contour—like swelling, shrinking, or bulging—could signal something more than just natural fluctuations.
3. Skin Dimpling or Puckering
If the skin on your breast starts to dimple, pucker, or resemble an orange peel, it could be a sign of an underlying tumor pulling at the skin. This condition, known as peau d’orange, is often linked to more aggressive forms of breast cancer.
4. Nipple Discharge (Other Than Breast Milk)
While nipple discharge can occur for many reasons, a discharge that is spontaneous, bloody, clear, or occurring without squeezing the nipple should raise a red flag. It’s essential to have any unusual nipple discharge evaluated, particularly if it’s persistent.
5. Nipple Changes or Retraction
A nipple that suddenly inverts, flattens, or changes direction can be another sign of breast cancer. If your nipple was previously outward and begins pulling inward (nipple retraction), this may be caused by changes in the tissue behind the nipple due to a growing tumor.
6. Persistent Breast or Nipple Pain
Breast cancer doesn’t typically cause pain in its early stages, but persistent pain in the breast or nipple that doesn’t seem to go away could signal a problem. It’s always best to get unusual pain checked, especially if it’s isolated to one breast.
7. Redness, Scaling, or Thickening of the Skin
If the skin on your breast becomes red, inflamed, or starts to thicken and scale—especially around the nipple—it may be a symptom of inflammatory breast cancer. This rare but aggressive form of the disease can also cause the skin to feel unusually warm.
8. Swelling or Lumps Near the Collarbone or Armpit
Breast cancer can spread to lymph nodes before you feel a lump in the breast. Swelling or lumps in the armpit or near the collarbone may indicate that the cancer has spread to nearby lymph nodes. Even if there’s no lump in the breast, these changes warrant an immediate check-up.
Take Action: Early Detection Saves Lives
If you notice any of these signs, don’t wait. Schedule a visit with your healthcare provider right away.
Get your mammograms early. Most women start at age 40, but depending on your family history you may need to start earlier. Do self breast exams, monthly, know your own breasts and watch out for these signs.
Here are some key breast cancer statistics in the U.S., based on the most recent data:
Incidence:
Breast cancer is the most common cancer among women in the U.S. (excluding skin cancers).
In 2023, an estimated 297,790 new cases of invasive breast cancer and 55,720 cases of non-invasive (in situ) breast cancer were expected to be diagnosed in women.
About 1 in 8 women (12.9%) in the U.S. will develop invasive breast cancer over the course of her lifetime.
Although less common, 2,800 cases of breast cancer are expected to be diagnosed in men each year.
Mortality:
Breast cancer is the second leading cause of cancer death in women, after lung cancer.
In 2023, an estimated 43,700 women were expected to die from breast cancer in the U.S.
On average, about 1 in 39 women (3%) will die from breast cancer.
Survival Rates:
The 5-year relative survival rate for women with localized breast cancer (no spread beyond the breast) is 99%.
If the cancer has spread to nearby lymph nodes, the 5-year survival rate drops to 86%.
For women with distant (metastatic) breast cancer, the 5-year survival rate is 30%.
Early Detection:
Mammograms have helped reduce breast cancer mortality by about 40% since they became more widely used, due to earlier detection and better treatment options.
When detected early, breast cancer has a significantly higher survival rate, which emphasizes the importance of regular screenings.
These statistics underline the prevalence of breast cancer in the U.S. and the importance of early detection and treatment. While survival rates have improved due to advancements in treatment and awareness, the disease still represents a major health concern.
