testicles usually descend by term birth but w/ this disease the testicles do not descend during the first 3 months of life
the higher the testicle, the higher the risk for developing cancer & if correction is not done by 12yrs, person has 2x higher risk
+in 25% of cases the cancer develops in the testicle that descended
what are the two types of germ cell tumors
seminomas & nonseminomas
germ cells are
the sperm forming cells in the testicles
seminomas germ cell cancer
-arise from immature germ cells
-slow growing, nonaggressive
-easily cured w/ radiation
nonseminomas germ cell cancer
-arise from mature germ cells
-more aggressive
-usually treated w/ surgery
early clinical manifestations of testicular cancer (4)
-enlargement of testicle
-painless mass noted
-ache in groin
-sensation of heaviness
95-99% survival rate at this stage
late clinical manifestations of testicular cancer
-possible frank pain
-manifestations based on spread:
cough, hemoptysis, swelling of lower extremities, back pain & dizziness
still 75% survival rate
the prostate
-gland surrounding the urethra
-produces seminal fluids
-weighs between 4-20g
how much can the prostate weigh w/ BPH
up to 50-80g
BPH
nonmalignant enlargement of prostate caused by excessive growth of epithelial cells & smooth muscle cells
the overgrowth of epithelial cells in BPH cause
a mechanical obstruction of the urethra
the overgrowth of smooth muscle cells in BPH cause
dynamic obstruction of the urethra
risk factors of BPH (3)
-age
-family hx
-race/ethnicity (highest in AA, lowest in asian)
