Dr. Leondires brought this to my attention yesterday. News we all want to hear; that trying to conceive a child and using advanced reproductive technologies do not seem to cause cancer. It's being picked up by news agencies all over the world as it's really the best news possible.
We want our families, but at what risk? Even if we were willing to take the risk of illness for ourselves, it's only fair to ask about how that would effect the child that we have brought into this world. Ironic that we even have to question that the medicine and treatments that could create a child could also create disease. How does anyone make that choice? Why should anyone have to?
The good news, as being celebrated the world over, is that you don't have to choose between a child and possible cancer. Read on to see exactly what the report has to say :

NEW YORK (Reuters Health) Dec 02 - Fertility treatment may not be tied to an increased risk of cancer, suggests a new study from Sweden.
Some prior studies had suggested that fertility drugs might be linked with breast, uterine and ovarian cancers, but the numbers of women followed in these studies were small, said lead researcher Dr. Bengt Kallen of the University of Lund in e-mail to Reuters Health.
In new research reported online November 18th in Human Reproduction, Dr. Kallen and colleagues analyzed registry data from 1982-2006 on 24,000 women who gave birth after in vitro fertilization (IVF). They compared rates of cancer in these women and in 1.4 million women in the general Swedish population who also gave birth in those years.
Fewer than 2% of women in the IVF group developed one or more cancers during an average follow-up of 8 years, vs close to 5% of the control group.
After accounting for maternal age, number of previous pregnancies, and smoking status, the overall risk of cancer was about 25% lower for women who had IVF.
"A couple who needs IVF does not have to be afraid that the hormone treatment used -- at least those used in Sweden -- will carry a risk for the woman to develop cancer," Dr. Kallen told Reuters Health.
The risk of ovarian cancer was more than twice as high in the women who had IVF as in those who didn't, however. Dr. Kallen suggests this may be due to abnormalities in ovarian function, which both increase the risk for infertility -- and therefore the need for IVF -- and the risk for cancer.
"The risk for two common cancers, breast and cervical, was significantly lower than expected," Dr. Kallen said.
Dr. Kallen also offered two possible explanations for these surprising findings: women who got IVF may have been healthier than average, or perhaps more likely, IVF-treated women may undergo more mammography and cervical exams.
The only fertility drugs currently used with IVF in Sweden are gonadotropins. Prior to the mid-1990s, these drugs were used in combination with another treatment, clomiphene.
Gonadotropins are also the primary fertility hormones prescribed today in IVF clinics across the U.S. Clomiphene is used only very rarely, Dr. Helen Kim, Director of the In Vitro Fertilization Program at The University of Chicago, told Reuters Health.
Despite some concern regarding the relatively homogenous population of Sweden, Dr. Kim - who wasn't involved in the study - believes its findings should be fairly generalizable.

LONDON — Overweight women have a much higher risk of a miscarriage after having in-vitro fertilization compared with slim women, new research says.
Doctors have long known that heavy women are more prone to having a miscarriage and suffering other complications after becoming pregnant naturally, but there has been conflicting data over whether that was also the case after using artificial reproduction techniques.
British doctors tracked all 318 women at a London clinic who became pregnant after having in-vitro fertilization from 2006 to 2009, then divided the women according to their Body Mass Index. Women who had a BMI of 18 to 24 were classified as normal. Those who had a BMI of 25 or above were considered overweight, while those above 30 were obese.
After making a statistical adjustment for factors that might have skewed the results — such as age, smoking and medical history — the researchers found overweight and obese women were much more likely to have a miscarriage as thin women.
The research was presented Monday in Rome at a meeting of the European Society of Human Reproduction and Embryology.
Among women with a normal weight, 22 percent using in-vitro at the clinic had a miscarriage. But among overweight and obese women, the risk of a miscarriage was 33 percent.
For women who have conceived naturally, the miscarriage rate can range from 4 percent to 23 percent during the first trimester, depending on their age and medical history. Experts say the risk for overweight and obese women conceiving naturally can be three to four times higher than the average for regular weight women.
"One of the best fertility treatments is weight loss," said Dr.Richard Grazi, director of reproductive endocrinology and infertility at Maimonides Medical Center in New York, who was not linked to the study.
"With the obesity epidemic, we are constantly counseling patients to lose weight if they want to have IVF," he said. "Our goal is not only that they get pregnant, but that they stay pregnant."
At Grazi's U.S. clinic, patients with a BMI above 35 are not eligible for in-vitro fertilization. At many hospitals across Europe — where at least one cycle is paid for by governments — the cut-off is often lower, at a BMI of 30.
Doctors aren't sure why excess body weight makes pregnancy more risky, but suspect fat may have harmful effects on the lining of the uterus, making it difficult for embryos properly implant.
"Fat doesn't just sit there, it's very dynamic and sends out hormones and other signals that affect the rest of your body," Grazi said.
"Our aim was not to exclude women from getting treatment, but to help women get the best outcome after they have IVF," said Dr. Vivian Rittenberg, a clinical fellow in the Assisted Conception Unit at Guy's and St. Thomas' Hospital in London, who led the study. She said overweight and obese women pursuing artificial reproduction techniques should get more help losing weight first.
Other experts agreed the findings should spur heavy women to drop a few pounds before pursuing in-vitro fertilization, a costly and invasive process that can last for months. Only about one in four couples pursuing IVF end up with a baby, and being heavy can reduce those odds even further.
"Overweight and obese women have poorer outcomes at nearly every stage of pregnancy," said Dr. Daghni Rajasingam, an obstetrician and spokeswoman for Britain's Royal College of Obstetricians and Gynaecologists.
Rajasingam said overweight or obese women are also at higher risk for developing diabetes while pregnant, which in turn raises the chance of a miscarriage.
She said women should realize losing weight could make a big difference to having children.
"If you optimize your body weight so that your BMI is normal, your chances of having a baby to take home are much higher," Rajasingam said.
Around the world, infertility and fertility treatment is making news.
