There are many types of pancreas tumors, and correctly identifying each one is important to determine the proper treatment. The terms "tumor" and "cancer" are sometimes used interchangeably, which can be misleading. A tumor is not necessarily a cancer.

Tumors are sometimes cancerous but this does not mean that tumors and cancers are synonyms as most people think. Though all lumps are not cancerous, a few of them are. So a proper examination of lumps is very important.

Cancer vs. Tumor

A tumor is a mass or lump of tissue that may resemble swelling. Not all tumors are cancerous, but it is a good idea to see a doctor if one appears. In a healthy body, cells grow, divide, and replace each other in the body. As new cells form, the old ones die. When a person has cancer , new cells form when the body does not need them. If there are too many new cells, a group of cells, or tumor, can develop.

Cancer vs. Tumor

Medically reviewed by Robert J. Mayer, MD. Cancer is a disease in which cells, almost anywhere in the body, begin to divide uncontrollably. A tumor is when this uncontrolled growth occurs in solid tissue such as an organ, muscle, or bone. Tumors may spread to surrounding tissues through the blood and lymph systems.

Cancer can start almost anywhere in the human body, which is made up of trillions of cells. Normally, human cells grow and divide to form new cells as the body needs them. When cells grow old or become damaged, they die, and new cells take their place. When cancer develops, however, this orderly process breaks down.

A tumor also called neoplasm is an abnormal mass of cells in the body. It is caused by cells dividing more than normal or not dying when they should. Tumors can be classified as benign or malignant. Benign tumors are those that stay in their primary location without invading other sites of the body. They do not spread to local structures or to distant parts of the body. Benign tumors tend to grow slowly and have distinct borders.

Benign vs Malignant Tumors

A benign tumor is a mass of cells tumor that lacks the ability to either invade neighboring tissue or metastasize spread throughout the body. When removed, benign tumors usually do not grow back, whereas malignant tumors sometimes do. Unlike most benign tumors elsewhere in the body, benign brain tumors can be life-threatening. Although benign tumors will not metastasize or locally invade tissues , some types may still produce negative health effects.

Abnormal Cellular Growth

Он ни разу не посмотрел по сторонам. - Это так важно? - полувопросительно произнес Джабба. - Очень важно, - сказал Смит.  - Если бы Танкадо подозревал некий подвох, он инстинктивно стал бы искать глазами убийцу. Как вы можете убедиться, этого не произошло. На экране Танкадо рухнул на колени, по-прежнему прижимая руку к груди и так ни разу и не подняв глаз. Он был совсем один и умирал естественной смертью.

Сьюзан посмотрела на решетчатую дверь, ведущую в кухню, и в тот же миг поняла, что означает этот запах. Запах одеколона и пота.

Неужели она узнала. Этого не может. Стратмор был уверен, что предусмотрел. - Сьюзан, - сказал он, подходя ближе.

На этот раз ему очень вежливо ответили по-немецки, но снова сказали, что рыжих девочек у них. - Keine Rotkopfe, простите.  - Женщина положила трубку.

    The major dilemma of cancer chemotherapy has always been a double-edged sword, producing resistance in tumor cells and life-threatening destruction of nontumorigenic tissue.
