Mast cell tumors are the most common skin tumor found in dogs (The National Canine Cancer Foundation). According to the ASPCA Complete Guide to dogs mast cell tumors are‚ “solitary masses on the surface of the skin and in the tissue immediately under the skin” (Gerstenfeld and Schultz‚ p. 431). Essentially if a dog has a mast cell tumor‚ then that dog has cancer. There are three types grades for these tumors. The first grade is when it occurs in the skin‚ is non-malignant and do not spread.

bloodstream or lymphatic system and then to other sites in the body. This process of spread is termed metastasis; the areas of tumor growth at these distant sites are called metastases. Since lung cancer tends to spread or metastasize very early after it forms‚ it is a very life-threatening cancer and one of the most difficult cancers to treat. The lung also is a very common site for metastasis from tumors in other parts of the body. Tumor metastases are made up of the same type of cells as the original

During the 20th century‚ the element radium was used for commercial purposes and medicinal.

The owners of the company preached the benefits of the drink and that it could possibly increase sexual desire. In this way‚ many people

Difference in lymphatic function in health and disease state The lymphatic vascular system has an important role in tissue pressure and immune system. The lymphatic system also contributes to a number of diseases such as lymphedema‚ cancer metastasis and many other different inflammatory disorders. Lymphatic obstruction is a blockage of the lymph vessels which drain fluid from tissues through your body. Also allows immune cells to travel where they are needed. Lymphatic obstruction may cause

The two major brands of violent jihadism‚ IS and al-Qaeda‚ compete for the allegiance of various groups of African jihadists. Yet the connections between groups are more complex than mere pledges of fealty. Cross-border links often originate paradoxically not when extremists are strong‚ but when they are weak. During a crackdown on Boko Haram in 2009 many of its leaders went to Chad‚ Sudan and Somalia. Since then Sudanese Arabic voices have been heard in Boko Haram propaganda videos. The group’s
