Sarcoma, The Cancer Of Connective Tissues

Sarcoma is a rare cancer in adults (1% of all adult cancers), but  prevalent in children (about 20% of all childhood cancers). It is made up of many “subtypes” because it can arise from a variety of tissue structures (nerves, muscles, joints, bone, fat, blood vessels – collectively referred to as the body’s “connective tissues”). Because these tissues are found everywhere on the body, Sarcomas can arise anywhere. Thus, within each site of the more “common” cancers there is the occasional surprise sarcoma diagnosis (e.g., breast sarcoma, stomach sarcoma, lung sarcoma, ovarian sarcoma, etc.). The most frequent location are the limbs since this is where the majority of the body’s connective tissue resides. They are commonly hidden deep in the body, so sarcoma is often diagnosed when it has already become too large to expect a hope of being cured. Although a lot of the lumps and bumps we get are benign, people should have them looked at by a doctor at an early stage in case it is sarcoma.

Overview of Skin Cancer Tumors – Melanoma – Squamous Cell Carcinoma – Basal Cell Carcinoma

Each year in the U.S. over 5.4 million cases of non melanoma skin cancer are treated. Skin cancer is the most common of all human cancers. Cancer occurs when normal cells transform, grow and multiply without normal controls. They form a tumor. Tumors are cancerous only if they are malignant. They encroach on and invade neighboring tissues. Continue reading

The Growth of Cancer Cells and Cancer Stem Cells

Cancer cells are cells gone wrong, in other words, they no longer respond to many of the signals that control cellular growth and death as described in the Krebs Cycle. Cancer cells originate within tissues and, as they grow and divide, they change even further from normalcy.

Over time, these cells become increasingly resistant to the controls that maintain normal tissue and as a result, they divide more rapidly than their progenitors and become less dependent on signals from other cells. Cancer cells even evade programmed cell death, despite the fact that their multiple abnormalities would normally make them prime targets for apoptosis. In the late stages of cancer, cells break through normal tissue boundaries and metastasize (spread) to new sites in the body. Continue reading

What Happens to Dead Cancer Cells In the Human Body

When a Cancer cell is killed or dies an immune response occurs. This means many things are happening that are involved with the immune system. One of the bodies many partners in the immune system is the macrophage cell. A macrophage cell can literally detect dead cells through smell, much like a scavenger bird detects dead animals. Whenever dead cells reach the part of the bloodstream patrolled by Continue reading
