Study Notes
Benign versus Malignant Tumors
-
Benign tumors resemble the tissue of origin
-
Grow progressively slowly
-
Remain localized; cohesive cells
-
Not invasive; do not destroy surrounding tissue
-
Do not break away from the tumor cell mass
-
No metastasis
-
Malignant tumors range from well-differentiated to poorly differentiated
-
Poorly differentiated do not resemble tissue of origin
-
Grow erratically; faster than benign tumors
-
Invasive and destructive to surrounding tissue
-
Lack adhesion; easily travel to distant sites via metastasis
-
Common locations for metastasis include the lymphatic system or bloodstream
Staging of Malignant Tumors
- Stage I: localized
- Stage II: early locally advanced
- Stage III: late locally advanced
- Stage IV: metastasized
Apoptosis
- Genetically programmed cell death
- Example in ovaries during menopause
- Example in WBCs after inflammatory reaction
- Failure in apoptosis can lead to cancer or tumors
- Excessive apoptosis can lead to excessive cell death
