people with a prostate ages 50-70 should get a digital rectal exam every 3 years
what are the 3 stages of cancer pathology
Initiation
Promotion
Progression
what is involved in the initiation phase of cancer pathology
mutation in the cell’s genetic structure resulting from an inherited mutation, an error that occurs during DNA replication or after exposure to a carcinogen
what is involved in the promotion phase of cancer pathology
the second stage in the development of cancer, is characterized by the reversible proliferation of the altered cells.
what is involved in the progression phase of cancer pathology
when the tumor growth rate increases and metastasis start to occur
what are some of the most common sites for cancer metastasis
Brain
Bone
Liver
Adrenal Gland
what are 4 key factors that can initiate cancer
-Chemical
-Radiation
-Viral and bacterial carcinogens
-Genetic susceptibility
what does carcinoma mean
cancer that starts on the skin or on the tissue that lines or covers internal organs
what does sarcoma mean
cancer of the connective tissue
what structure in the body does leukemia affect
Cancer of the bone marrow
What is stage 0 cancer
when the cancer is in situ and contained
what is stage 1 cancer
Tumor limited to the tissue of origin; localized tumor growth
what is stage 2 cancer
Limited local spread
what is stage 3 cancer
Extensive local and regional spread and the tumor has most likely gown out of the organ it started in to nearby tissue/lymph
what is stage 4 cancer
the cancer has spread through the blood or lymph to a distant site in the body to form metastasis
what are the four classifications of tumor size according to TNM grading scale
TX: unable to measure tumor
T0: No evidence of tumor
TIS: Tumor hasn’t grown into nearby tissue
T1-T4: tumor has grown into nearby tissue to varying degrees
What are the three classifications of lymph node involvement according to the TNM grading scale
NX: unable to evaluate lymph nodes
N0: No cancer found in the lymph nodes
N1-N3: Cancer has spread into lymph nodes to a varying degree
what are the two classifications for metastasis in the TNM grading system
M0 or M1
either it has or hasn’t spread
