It is there that the electrical impulses are interpreted into sight. Damage to the optic nerve interrupts this flow of visual information. In glaucoma, researchers believe that the ganglion cells of the retina, as well as the support cells within the optic nerve, can die for various reasons.
If you have had breast-conserving surgery, you need to continue to get mammograms. If you have had a mastectomy, you may not need a mammogram. Regardless of what breast cancer surgery you have had, you will still need to get mammograms of the unaffected breast. This is very important, because women who have had one breast cancer are at higher risk of developing a new cancer in the other breast.
Mammograms are easier to read in older women because their breast tissue has more fatty tissue than that of younger women. It's easier for an X-ray to go through fatty tissue than dense tissue. This is one of the reasons that mammogram screening is not routinely recommended in women under 40 years of age.n ultrasound of the breast can show all areas of the breast, including the area closest to the chest wall, which is hard to see with a mammogram. While ultrasound can help locate breast problems, it is not a substitute for a mammogram. It is often used in addition to a mammogram to evaluate a breast problem.
