Redness of the Breast
This is the sign of breast cancer you can see with your eyes. The redness looks like eczema, but it doesn't go away and becomes larger.
This type of breast cancer doesn't form a lump and is called Inflammatory Breast Cancer.
Cancer cells break the wall of the milk duct, goes into lymph ducts, and spread out the whole breast without forming a big lump.
The redness appears because lymph ducts are clogged by cancer cells and the flow of lymph is interrupted, causing the inflammation.
Inflammatory breast cancer is a very rare type of cancer, but it metastasizes to other part of the body such as lymph nodes or the lung about 1 month after the redness of the breast appears.
So it is important not to miss the appearance of the redness of the breast.
