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.

United we can eradicate the problem

Every year, worldwide, October is the Breast Cancer Awareness Month. Each year, there are nearly 1.38 million cases and nearly 450 000 deaths from breast cancer. According to the World Health Organization, this type of cancer is the most common in women worldwide. According to the Office of Disease Prevention And Health Promotion, about 1 in 8 women in the United States will get breast Cancer at some point.

Leukemia-Causes, Symptoms And How To Prevent It

Leukemia is a type of cancer found in  blood, bone marrow and is caused by the rapid production of abnormal white blood cells. These abnormal white blood cells are not able to fight infection and impair the ability of the bone marrow to produce red blood cells and platelets.
Leukemia is actually a group of different cancers of the blood cells. Leukemias can be acute or chronic, and people with chronic leukemias may not notice any symptoms before the condition is diagnosed with a blood test.

Cancer Risks And Obesity

There is research suggesting the impact obesity has on the development of certain cancers.

According to  Sir Richard Doll and Richard Peto, 35% of cancer deaths in the USA might be linked to diet. This is particularly certain for endometrium and breast cancer.

The Washington School of Medicine, submitted a  document which explains obesity accounts for about 20% of all cancer cases.

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

Free Radicals in the Body – Oxidative Stress and the Antioxidant Response

The basic science of oxidative stress and the antioxidant response is not in contention, what is an effective antioxidant is. When the body breaks food down into energy, it generates a by-product known as free radicals. Also present in food itself, the air we breathe and the sun we worship, free radicals are a broad class of chemicals with the potential to exert significant damage. By ‘stealing’ electrons from nearby molecules, free radicals in the body may tamper with DNA and impede normal cell function. 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
