Most benign tumors grow slowly . & most of cancers grow faster . & eventually spread locally & to distant sites (metastasis) & causing death.. In some exception, some benign tumors grow more rapidly than some cancers e.g. leiomyoma (uterine fibroid), which is benign smooth muscle tumor influence by estrogen & so increase in size during pregnancy.. LEC.1. General Features . Inflammation is defined as "the response of living . vascularized. tissues to harmful agents.”. . It consists principally of vascular changes associated with leukocytes infiltration and systemic reactions. LEC.4. Examples of tumor suppressor genes:. 1. RB gene:. This is the . first discovered suppressor gene. , . loss of normal RB gene was discovered initially in Retinoblastoma, but recently proved it lost in many tumors (breast cancer, bladder & lung cancer, osteosarcoma).. LEC.3. Incidence of cancer. In male. . 30% Carcinoma of prostate. .. 14% Carcinoma of Lung.. 11% Carcinoma of colon & rectum.. In female. . . 31% breast carcinoma. .. 12% carcinoma of lung. . LEC.5.

(. active without transformation in the body). LEC.1. Abnormal mass of tissue. , characterized by followings:- . Its . growth is uncoordinated & exceeded. with that of the normal tissues.. Neoplasm . persist its growth after the cessation of stimuli which cause the change.. LEC.4. Carcinogenesis:. is a multistep process at both . phenotypic & genetic levels.. Phenotypic level . includes:. I. Excessive growth.. II. Local invasion.. III. Metastasis.. These three criteria are called collectively . LEC.5. 3. Evasion of apoptosis:. Normally, . the mechanism of . apoptosis is mediated by many genes, & achieve by two phases. . Initiation phase. , which is mediated by . TNF- Fas receptor . & inhibited by FLIP protein..
