Because obesity is known to increase a woman's risk
of endometrial cancer by 200 percent, a team of researchers led by oncologist Leena Hilakivi - Clarke of Georgetown Lombardi Comprehensive Cancer Center in Washington, D.C., decided to examine the development of endometrial cancer in obese mice to that in non-obese mice.
The findings reveal that every 5 years of oral contraceptive use reduces the risk
of endometrial cancer by about a quarter.

By contrast, in more than 90 %
of endometrial cancers, the gene has undergone hypermethylation, an epigenetic modification that doesn't change its DNA sequence but renders it inactive.
We identified patients with mutations that predict phenomenal outcomes in the disease; this is a group
of women with
endometrial cancer who won't need the financial, physical or emotional toll
of chemotherapy at all — they're patients who are probably cured
by surgery alone.
However, James notes, a review
of data
by the World Health Organization's International Agency for Research on
Cancer last February concluded that between a quarter and third
of all colon, breast,
endometrial, kidney, and esophageal
cancers globally may trace to excess weight, especially obesity.
Researchers from the Collaborative Group on Epidemiological Studies on
Endometrial Cancer estimate that in the past 50 years (1965 - 2014) about 400000 cases of endometrial cancer have been prevented by oral contraceptive use in high - income countries, including about 200000 in the last decade (20

Permanent discontinuation
of study medication was required
by protocol for women who developed breast
cancer,
endometrial pathologic state (hyperplasia not responsive to treatment, atypia, or
cancer), deep vein thrombosis (DVT) or PE, malignant melanoma, meningioma, triglyceride level greater than 1000 mg / dL (11.3 mmol / L), or prescription
of estrogen, testosterone, or selective estrogen - receptor modulators
by their personal physician.
Potential cardioprotection was based on generally supportive data on lipid levels in intermediate outcome clinical trials, trials in nonhuman primates, and a large body
of observational studies suggesting a 40 % to 50 % reduction in risk among users
of either estrogen alone or, less frequently, combined estrogen and progestin.2 - 5 Hip fracture was designated as a secondary outcome, supported
by observational data as well as clinical trials showing benefit for bone mineral density.6, 7 Invasive breast
cancer was designated as a primary adverse outcome based on observational data.3, 8 Additional clinical outcomes chosen as secondary outcomes that may plausibly be affected
by hormone therapy include other cardiovascular diseases;
endometrial, colorectal, and other
cancers; and other fractures.3, 6,9
Some
cancers: Women on the pill reduce their risk
of colon
cancer by 14 percent and
endometrial cancer by 43 percent, per a 2013 study.
Next, we found that the increase
of p21Cip1 / WAF1 expression, which occurs upon LA exposure in a p53 - independent manner, is involved in the apoptotic effects prompted
by LA in both breast and
endometrial cancer cells.
WHI Study (Second Arm): All the women in the second arm
of the WHI study had prior hysterectomies (uterus absent), so they did not need the synthetic progestin, called Provera, which is required to prevent the
endometrial cancer caused
by Premarin alone.
Over many years,
endometrial cancer may result due to continuous stimulation
by high levels
of estrogen unopposed
by progesterone, causing the uterine lining to thicken and fail to properly shed.
This reduction in risk may also extend to ovarian and
endometrial cancers, two other types
of cancer that are influenced
by hormones.
Obesity causes elevated amounts
of estrogen (secreted
by fat cells) which can drive genesis
of certain
cancers like breast and
endometrial cancer
Moreover, estrogen imposes a risk
of endometrial cancer that is largely preventable
by progesterone and its analogues.
In clinical trials, Raloxifene (also used for osteoporosis) has been shown to cut the risk
of breast
cancer by 70 percent without causing
endometrial cancer.
