- M: Attached to surrounding tissue and deeply fixed in surrounding tissue
-
Benign VS. Malignant: Shape
- B: Smooth and round with a surrounding fibrous capsule
- M: Irregular shaped with no capsule
-
Benign VS. Malignant: Cell Growth
- B: Cell multiply slowly
- M: Cell multiply rapidly
-
Benign VS. Malignant: Tumor Growth
- B: Tumors grow by expanding and pushing away & against surrounding tissue
- M: Tumors grow by invading and destroying
- surrounding tissue
-
Benign VS. Malignant: Metastasis
- B: Never spread to other sites (metastasized)
- M: Almost always spread to other sites if not removed or destroyed.

Benign VS. Malignant: Prognosis
-
A cancer that develops in the tissues that support and connect the body. It can occur in fat, muscle nerves, tendons, joints, blood vessels or lymph vessels
Sarcoma
-
Cancer that arises from epithelial cells
Carcinoma
-
Ca that begins in the lymph nodes and immune system tissue
Lymphoma
-
Ca that arises in the thyroid , pituitary gland, adrenal glands and other glandular tissue
Adenoma
-
ABCDE of moles
- Asymmetry
- Color changes
- Diameter bigger than 5mm
- Evolving
-
a cancer staging system that describes the extent of Ca in a patient’s body.
Malignant
-
TNM Classification of Malignant
- T describes the size of the tumor and whether it has invaded nearby tissue
- N describes regional lymph nodes that are involved
- M describes distant metastasis (spread of cancer from one body part to another)
-
indicates the size and direct extent of the primary tumor
T(1-4)
-
indicates the degree to which the cancer has spread to nearby lymph nodes
N (0-3)
-
indicates whether the cancer has metastasized to other organs in the body
M (0-1)
-
Small tumor that has not spread to lymph nodes or distant organs may be staged as
(T1, N0, M0)
