I've heard there is a penalty if I don't enroll in Medicare when I turn 65. If covered under an employer's group health plan, you will have 8 months from the time your coverage ends to enroll in Medicare Part B without penalty. For Medicare Part D, you will have 63 days.
Lymph nodes are small bean-shaped structures that are usually less than 2.5 cm in length. They are widely distributed throughout the body along the lymphatic pathways where they filter the lymph before it is returned to the blood.Lymph nodes are not present in the central nervous system.There are three superficial regions on each side of the body where lymph nodes tend to cluster.ymph nodes are small bean-shaped structures that are usually less than 2.5 cm in length.

One main lymph node area (the armpit, or axilla) and two secondary lymph node areas (the internal mammary and supraclavicular regions) filter the lymph fluid draining away from the breast area. Since the job of the lymph nodes is to filter out bad guys like cancer cells, this is a logical place to look for breast cancer cells that have escaped the original tumor and are trying to go elsewhere in the body. Cancer cells may also leave the breast through the bloodstream and bypass the lymph nodes.
