In fact, the role of self-examination by women is very limited. Sometimes it can delay the diagnosis. Not to mention the difficulty of self-examination, even if you learn, it may not be useful. Because in the middle of women’s breast, there is a relatively dense breast glandular tissue with certain thickness and hardness. If there is a tumor of 1~2 cm in diameter growing in it, then the growth position can be roughly divided into three cases: 1. growing on the surface of the gland and protruding from the surface; 2. growing in the middle of the gland; 3. growing on the back of the gland. The first case is likely to be detected by touch earlier, while in the second and third cases, it is difficult to detect by touch because the mass is about the same hardness as the gland. There is no doubt that if such small masses are examined by palpation alone, then a missed diagnosis is inevitable. However, a lump of this size can be clearly detected by ultrasound. Moreover, breast tumors are not only manifested by lumps, but also by foci of calcification, which cannot be detected by touch at all in the early stage. Therefore, self-examination of women’s breasts mostly detects middle and late stage tumors, but not early stage diseases. Therefore, friends, in order to care for your health, you should dispel all kinds of worries and go to the relevant hospital specialties for regular checkups in order to diagnose and treat breast diseases at an early stage. Be happy and healthy.
