Yes, it is possible to have breast cancer and not know. Although this may seem unlikely, mammograms can sometimes miss cancer or identify it too late for a cure. Breast cancer can also be symptomless during the early stages or present with symptoms that are mistaken for other conditions. A study published in the journal Cancer Epidemiology, Biomarkers & Prevention found that up to 20% of all women diagnosed with breast cancer had no noticeable signs or symptoms at detection.
This is why it's so important for individuals to receive regular screening through mammograms and physical exams as recommended by their healthcare provider. Additionally, being aware of any changes in your breasts regarding lumps or other unusual signs is important and should always prompt a visit to your doctor for further investigation. In general, individuals at risk should check both their breasts every month using BSE (breast self-examination) which involves feeling each area with the pads of your fingers while lying down or standing up in front of a mirror checking visually as well if anything looks off color compared to the rest of the area.
Early detection increases treatment options and prognosis so getting educated about what’s normal for you and taking preventive measures saves lives!
