The most common symptom of breast cancer is the presence of painless lumps in the breast. As the cancer progresses, additional symptoms may develop, including breast pain, lumps in the breasts or armpits, nipple discharge, and changes to nipple appearance.

Breast cancer screening is conducted using a mammogram, which utilizes X-rays to detect any abnormal changes in the breasts. The test typically takes about 10 minutes and may be uncomfortable due to the compression of the breasts. However, it is crucial to compress the breast as much as possible to allow the X-rays to more effectively detect any potential cancer.

Breast cancer is the leading cause of cancer-related deaths among women worldwide. It has a high recurrence rate and commonly spreads to other organs. However, if detected early, survival rates are high and advancements in medicine have made breast-preserving treatments available.
Stage 0-2 breast cancer has a 5-year survival rate of over 90% after surgery, whereas stage 4 has a survival rate of just 34%. Early detection through regular screening is crucial because symptoms are often not noticeable in the early stages.

A mammogram doesn't require you to fast or take any medication like other cancer screenings. You'll usually change into a gown in a changing room prior to the exam.
If you're breastfeeding or have had breast augmentation surgery, tell your provider ahead of time. Also, to improve the accuracy of the test, it's recommended that you don't use body lotion on your breasts on the day of the exam, and it's best to have the exam 5-7 days after your period ends, when your breasts are tender.

It is difficult to diagnose cancer based on mammogram results alone. If an abnormality is found on a mammogram, additional tests such as a localized mammogram or breast ultrasound are needed.
