invade surrounding tissues or travel
through the blood and lymphatic system.
Secondary tumor or metastases

muscle, cartilage and membranes covering muscle or fat.

Lymphomas:
Leukemia:

Testicular Cancer
The Cancer Society estimates that in the year 2006 about
8,010 new cases of testicular cancer will be diagnosed in
the United States.
An estimated 390 American men will die of testicular cancer
in the year 2005.

Prevention- Testicular self-exams
• Studies show that the cure rate exceeds 90% in all stages combined.
• The 5-year survival rate for stage I testicular cancer is 99%.

Screening Guidelines for the Early Detection of Breast
Cancer, American Cancer Society
 Yearly mammograms are recommended starting at age 40 and
continuing for as long as a woman is in good health.
A clinical breast exam should be part of a periodic health exam
-about every three years for women in their 20s and 30s
-every year for women 40 and older.
Monthly Breast self-exams for women starting in their 20s.
Women at increased risk (e.g., family history, genetic tendency,
past breast cancer) should talk with their doctors about the benefits
and limitations of starting mammography screening earlier, having
additional tests (i.e., breast ultrasound and MRI), or having more
frequent exams.
