| tumor | a new growth of tissue characterized by progressive,uncontrolled proliferation (growth)of cells.the tumor may be localized or invasive benign or malignant |
| stem cell | a formative cell;a cell whose daughter cells may give rise to to other cell types |
| staging | the determination phases or periods in the course of a disease |
| basal cell carcinoma | the most common malignant tumor of the epithelial tissue.it occurs most often on areas of the skin exposed to the sun |
| breast cancer (carcinoma of the breast) | a malignant tumor of the breast tissue.the most common type,ductal carcinoma,originates in the mammary ducts |
| colorectal cancer | the presence of a malignant neoplasm in the large intestine |
| bronchogenic carcinoma | a malignant lung tumor that originates in the bronchi;lung cancer |
| cervical carcinoma | a malignant tumor of the cervix |
| oral leukoplakia | a precancerous lesion occurring anywhere in the mouth |
| neuroblastoma | a highly malignant tumor of the sympathetic nervous system |
| malignant melanoma | malignant skin tumor originating from melanocytes in preexisting nevi(moles),freckles,or skin with pigment;darkly pigmented cancerous tumor |
| kaposi's sarcoma | rare malignant lesions that begin as soft purple-brown nodules or plaques on the feet and gradually spread throughout the skin |
| lymphoma | a lymphoid tissue neoplasm that is typically malignant-beginning with a painless enlarged lymph node & progressing to anemia,weakness,fever and weight loss |
| endometrial carcinoma | malignant tumor of the inner lining of the uterus;aka adencarcinoma of the uterus |
| squamous cell carcinoma | a malignancy of the squamous cells of epithelial tissue,which is a much faster growing cancer than basal cell carcinoma and has a greater potential for metastasis if not treated |
| renal cell carcinoma | a malignant tumor of the kidney,occuring in adulthood |
| prostatic cancer (carcinoma of the prostate) | malignant growth with the prostate gland,creating pressure on the upper part of the urethra. it most frequently diagnosed cancer in men |
| pancreatic cancer | a life-threatening primary malignant neoplasm typically the head of the pancreas |
| ovarian carcinoma | a malignant tumor of the ovaries most commonly occurring in women in their 50's |
| thyroid cancer (cancer of the thyroid gland) | malignant tumor of the thyroid gland that leads to dysfunction of the gland and thus inadequate or excessive secretion of the thyroid hormone |
| testicular cancer(carcinoma of the testes) | a malignant tumor of the testicle that appears as a painless lump in the testicle |
| tumors, primarily intracranial | tumors that arise from gilomas(malignant glial cells that are a support for nerve tissue)or from the meninges are known as primarily intracranial tumors |
| tumors,metastatic intracranial | tumors occurring as a result of metastasis from a primarily site such as the lung or breast |
| tumors,intracranial | occur in any structural region of the brain and may be malignant or benign.they are classified as primarily or secondary and are named according to the tissue from which they originate |
| wilm's tumor | a malignant tumor of the kidney occurring predominately in childhood |
| chemotherapy | the use of cytotoxic drugs and chemicals to achieve a cure,decrease tumor size,provide relief of pain or slow metastasis |
| mohs surgery | an advanced treatment procedure for skin cancer.the cancerous tumor is removed in stages,the tissue is examined for evidenced of caner,and additional tissue is removed until negative boundaries are confirmed |
| immunotherapy | agents that are capable of changing the relationship between a tumor and the host are known as biologic response modifiers (BRMs).these agents are used to strengthen the individuals immune responses |
| surgery | in more than 90% of all cancers,surgery is used for diagnosing and staging.in more 60% of all cancers,surgery is the primarily treatment.when feasible,the primarily tumor is excised in its entirety |
| radiation therapy | the use of ionizing radiation to interrupt cellular growth.the goal of radiation therapy is to reach maximum tumor control with minimum normal tissue damage |
