Ms M :hugs:

Time will put all this into perspective and your decisions made will be based on so much more than an emotional meeting. :hugs:

i went for a walk in my street this morning and a lady called Toni walked out with beanie on her head and came and said to me she had been hoping to meet me Toni is a grandmother and is going through BC for the second time in 18 months....meeting her is a blessing but also put fear in my head and heart about my own mortality and whether to have children? even though i have a excellent prognosis, what i am i suddenly so afraid and questioning the very thing that i've always wanted

do i risk having children and not be around to see them grow up because BC might come back? I will be judged for wanting to have children because of what i've been through so far?

this questions didnt faze me the past, so why now? :sniff: ..i mustnt let fear take hold and lose control..

however despite all the tears shed today, this post gave me a sense of relief...

EBCC: Pregnancy No Hazard to Breast Cancer Survivors

EBCC: Pregnancy No Hazard to Breast Cancer Survivors

In the United States, there are about 400,000 breast cancer survivors younger than 45. Many of these women might want to have children. The analysis reviewed here found that pregnancy doesn't negatively affect the future survival of women who've been diagnosed with breast cancer. These results were presented at the 2010 European Breast Cancer Symposium.

Hormones can promote the growth and spread of breast cancer. Hormone levels change during pregnancy, so doctors have been concerned that becoming pregnant after a breast cancer diagnosis might increase the risk of the breast cancer coming back or affect future survival. Some doctors have recommended that women not get pregnant after being treated for early-stage breast cancer.

The analysis reviewed here is called a meta-analysis because it analyzes the results of several different studies. The researchers looked at the information from 14 studies comparing health outcomes, including survival, of between about 1,400 breast cancer survivors who did become pregnant to about 18,000 breast cancer survivors who didn't become pregnant.

Overall, breast cancer survivors who became pregnant had a 42% survival improvement compared to survivors who didn't become pregnant.

Survival improvement ranged from 14% better to 79% better among the studies.
Researchers aren't sure why the women who got pregnant had better survival compared to women who didn't get pregnant. It could be that the improved survival seen among the women who became pregnant was due to better overall health and not because of being pregnant. So the researchers didn't jump to the conclusion that pregnancy after breast cancer treatment improves survival. Instead, their conclusion was that pregnancy doesn't negatively affect future survival among survivors.

If you're being treated for breast cancer or are a survivor and think you might want to become pregnant in the future, this study suggests that you can do so and not negatively affect your future survival.

BARCELONA (MedPage Today) -- For women who've had breast cancer, getting pregnant does not adversely affect survival and might even improve it, data from meta-analysis suggest.

Patients who became pregnant after breast cancer diagnosis had a 42% improvement in survival compared with breast cancer patients who did not become pregnant, Hatem A. Azim, Jr., MD, of Jules Bordet Institute in Brussels, reported here at the European Breast Cancer Conference.

But, although statistically significant, the risk reduction emerged from studies that appeared to have selection bias toward healthier patients.

"Breast cancer patients who want to get pregnant can go ahead and get pregnant," Azim said during a press briefing. "There is no evidence that pregnancy has any adverse effect on survival."

Early detection and effective treatment of breast cancer has led to a growing population of survivors, many of them still of child-bearing age. An estimated 400,000 breast cancer survivors in the United States are younger than 45, Azim said.

For many of those young women, pregnancy remains an issue with respect to its potential effects on continued breast cancer survival.

"Breast cancer is a hormonally driven tumor, and it is widely perceived that pregnancy in women with a history of breast cancer could have detrimental effects on breast cancer outcome by means of hormonal stimulation," Azim said.

Young breast cancer survivors often are counseled against pregnancy, and studies have suggested high rates of elective abortion among survivors who become pregnant, he added.

In an effort to clarify the risk that pregnancy poses to breast cancer survivors, Azim and colleagues reviewed the medical literature and identified 14 case-control studies that compared outcomes in breast cancer survivors who became pregnant and those who did not.

The studies comprised 1,417 pregnancies, and a control group of 18,059 women who did not become pregnant.

The results showed that pregnancy after breast cancer diagnosis was associated with a hazard ratio for overall survival of 0.58, representing a 42% reduction in mortality risk compared with the control group (95 CI 0.49-0.68).

All 14 studies resulted in hazard ratios that favored pregnancy for overall survival, ranging from 0.21 to 0.86. Eight of the studies yielded statistically significant differences in survival, as reflected in confidence intervals that did not include 1.00.

Although selection bias might explain some of the difference, some studies included in the analysis showed improved survival in analyses limited to control patients who did not have relapses during the study group's pregnancies.

Despite pregnancy's significantly favorable impact on mortality risk, Azim said, "I would not promote the results of the study as being protective because you cannot ask the patient to get pregnant as an effective means for breast cancer treatment. The concept is that breast cancer patients who want to get pregnant could go ahead and get pregnant. There is no evidence that this has any adverse effect on survival."

The reasons for the favorable effect of pregnancy on survival are unclear, he added. However, speculation about possible adverse effects of pregnancy have often centered on hormonal or immune processes that create a more favorable microenvironment for tumor cell growth.

Azim reported no disclosures.
