Once a woman goes through menopause, the glandular tissue is gradually replaced by fat, which is less dense. It is more difficult to read a mammogram if the breast tissue is dense so mammograms are not as reliable for younger women. Specialists have found that older women who take hormone replacement therapy HRT have denser breasts than would be expected for their age, which can make their mammograms less accurate. Most women are aware of the common risk factors when it comes to breast cancer.
However, many are not aware of the importance of breast density, which has been described as one of the most significant risk factors of all. Women with dense breasts have a higher proportion of fibroglandular and supportive tissue, whereas those with less dense breasts have a higher proportion of fat.
Unfortunately, breast density cannot be measured by look or feel, only by mammography, where dense breast tissue appears white and fatty breast tissue appears dark. Breast density cannot be measured by look or feel, only by mammography, where dense breast tissue appears white and fatty breast tissue appears dark. These are the women who are at risk of a cancer not being picked up by mammogram as dense breast look white on a mammogram and cancer looks white on a mammogram.
Currently, women in Ireland going through the BreastCheck mammographic screening programme are not routinely informed about their breast density when receiving their results, and many are unaware of this important risk-factor. It collects fluid, waste material, and other things such as viruses and bacteria that are in the body tissues, outside the bloodstream.
In the same way that veins collect and carry blood through the body, lymph vessels carry a watery yellow fluid called lymph. Lymph flows through the lymphatic system and eventually drains into veins. This system helps to get rid of waste products from the body. Lymph nodes are important in cancer care because any cancer cells that have broken away from a cancerous tumour can be carried by the tissue fluid to the nearest lymph nodes.
If your doctors finds a cancerous tumour, they will always examine your lymph nodes to see if there are cancer cells present there. If there are no cancer cells in the nearby lymph glands, your cancer is less likely to have spread. Sometimes lymph nodes become enlarged for other reasons that are not related to cancer e.
Your breast tissue extends to under your armpit. The armpits have many lymph nodes, also known as lymph glands. There is also a chain of lymph nodes that runs up the center of your chest, by your breast bone. This is called the internal mammary chain.
The diagram shows the network of lymph nodes around the breast. Because your breast tissue extends to your collar bone and your armpit, it is important to check these areas during your monthly breast self-examination. We hope you found this information useful.
