What is Cancer?
The body is made up of various kinds of cells, which normally divide in an orderly way to produce more cells only when they are needed. Cancer is a group of diseases - more than 100 types - that occur when cells become abnormal and divide without control or order. What is a Tumor?
When cells divide when new cells are not needed, too much tissue is formed. This mass of extra tissue, called a tumor, can be benign or malignant. |

Colorectal Cancer
Colorectal cancer is malignant cells found in the colon or rectum. The colon and the rectum are part of the large intestine, which is part of the digestive system. Because colon cancer and rectal cancers have many features in common, they are sometimes referred to together as colorectal cancer. Cancerous tumors found in the colon or rectum also may spread to other parts of the body (invade or metastasize). |

What is a hernia?
A hernia is the protrusion of an organ through the wall that normally contains it. Abdominal wall hernias are caused by a tear or defect in the abdominal muscle layers. The protruding organs cause a lump at the hernia site. Hernias usually occur in the weaker areas of the abdominal wall. These are the belly button, the groins and surgical scars. The belly button is the site through which embrionic blood vessels to the placenta pass through before birth, giving rise to umbilical hernias. The groin area in men is the site through which the blood vessels to the testicles pass leading to inguinal hernias. |

"Informed consent" is consent given by a patient only after having received detailed explanation regarding the proposed medical treatment. |

Often described as "varicose veins of the anus and rectum", hemorrhoids are enlarged, bulging, inflamed blood vessels in your anus and lower rectum. They may result from straining when having a bowel movement or the increased pressure on these veins during pregnancy. Many adults deal with the itching, bleeding and pain that often signal the presence of this condition. Fortunately, effective medications and procedures are readily available to treat hemorrhoids. In many cases this condition may require only self-care and lifestyle changes, with surgery reserved for larger, more severe cases. |
