How often should women do a breast exam? Is it necessary to do an annual examination or consult a doctor when there are already complaints? The topic is explained by Head of Mamology and Breast Surgery Service of MC Erebuni Dr. Nerses Beberyan. Breast cancer is the most common type of cancer. Despite this, the treatment rates are quite high. And the key is the early detection of cancer. The earlier the tumor is detected, the easier it will be to go through the treatment process. How can cancer be detected earlier? Before the age of 40, women should undergo an ultrasound exam once or twice a year, and after 40 years, a preventive mamographic examination is necessary. There is no need to be afraid of mammography. This makes it possible to detect cancer at the earliest stages.
