General Information
The
chances of having breast cancer are about 1 in 9 over a woman’s
lifetime.
The chances of having ovarian cancer are
about 7-8 times lower than breast cancer.
Despite the lower probability, ovarian
cancer kills more women than all other gynecologic malignancies
combined. Often ovarian cancer is not accompanied by symptoms until the
disease is advanced. In some cases, the early symptoms
of ovarian cancer can resemble those of the typical flu, which is why
women may disregard the symptoms until the cancer has reached the
advanced stage. Early stage ovarian cancer is very often curable and
advanced stage ovarian cancer carries a poor prognosis for survival;
however, beating ovarian cancer is dependent upon early detection.
Women with an elevated risk profile for
ovarian cancer (usually due to family history) are most likely to be
monitored or screened for ovarian cancer. However
the vast majority of ovarian cancers do not arise from women at high
risk because this group is small. Most ovarian cancers occur in women
who are over the age of 50 and do not have any symptoms. Ovarian cancer
screening of women over age 50 is not being recommended as a part of the
standard of care.
Symptoms like pelvic pain or abdominal
distension qualify women for diagnostic workups (not screening)
involving a bimanual pelvic exam and transvaginal ultrasound. Our
research protocol experience involving more than 30,000 women who have
received over 150,000 free ultrasound screens indicates that
transvaginal ultrasound is the most effective way to detect early stage
ovarian cancers and save lives.
Projected Costs
The costs of some different screening
tests for individuals are projected at:
A. Mammography: $150
B. Ovarian ultrasound: $150
C. PSA (prostate specific antigen): $85
Some professionals focus on the entire
cost of detecting a single cancer in a whole population. In thinking
this way, if 1 breast cancer is found on average in 10 women who are
screened, then the cost of detecting that 1 cancer would be said to be
10 women X $150 per screen = $1500.
For ovarian cancer, about 50 ovarian cancers will occur in every 100,000
women age 50 or over.
Thus, we could expect 1 ovarian cancer to turn up in every 2000 women
screened and the cost of detecting 1 ovarian cancer would be calculated
as:
2000 women X $50 per screen = $100,000
2000 women x $100 per screen = $200,000
2000 women x $150 per screen = $300,000
To achieve costs equivalent to the breast cancer population cost
estimate, a screening test for ovarian cancer would need to be as low as
$0.75
(i.e. 2000 women x $0.75/screen = $1500).
The costs to treat one woman with advanced
stage ovarian cancer (surgery, chemotherapy, palliative care) are
$200,000 or more, with outcomes unlikely to be successful.
