#2 – Changes in the breast size or shape
Besides the lump on the breast, which is one of the most obvious signs of male breast cancer, you may also notice a weird chance in the size or shape. You might experience a sudden increase in the size overtime or perhaps overnight!
Also, you may notice something abnormal happening under the skin, which is often painless, but it could cause slight changes to the area. These signs should not be taken for granted or to be neglected, so as soon as you notice this, check with your doctor ASAP!
