IVF process negatively impacts women’s sexual relationships

An Indiana University study has found that women undergoing in-vitro fertilization report that the process of infertility treatment has many negative impacts on their sexual relationship with their partner. Little attention has been given to the sexual dynamics of couples as they navigate infertility and treatments such as IVF, despite the important role that sex plays in a couple's attempt to conceive a child.

Social factors might explain racial and ethnic disparities in breast tumor aggressiveness

Racial and ethnic disparities in breast tumor aggressiveness might be explained by social factors that influence the developing tumor and place those in disadvantaged groups at higher risk for aggressive breast cancer, according to data presented at the Fifth AACR Conference on The Science of Cancer Health Disparities, held here Oct. 27-30, 2012.

AstraZeneca commences FASLODEX Phase III study for hormone receptor-positive metastatic breast cancer

AstraZeneca today announced the start of a Phase III study (FALCON), a global clinical trial which will involve 450 postmenopausal patients with hormone receptor-positive locally advanced or metastatic breast cancer who have not previously been treated with any hormonal therapy. The Phase III study is designed to evaluate the efficacy and tolerability of fulvestrant 500 mg compared to anastrozole 1 mg in this patient population.

Tumor count in the breast an important consideration for providing radiation therapy

Not all women diagnosed with operable breast cancer present with a single tumor; some have multifocal disease appear in the breast, which means multiple tumors found in the same breast quadrant, while others have multicentric disease, where multiple tumors are found in separate breast quadrants. Multifocal or multicentric disease is not a standard indication to receive radiation after mastectomy. For patients who undergo lumpectomy, radiation dose and extent is not altered based on multifocal or multicentric disease compared to patients presenting with a single tumor.

Post-radiation drop in testosterone linked to recurrence of prostate cancer in men

Men whose testosterone drops following radiation therapy for prostate cancer are more likely to experience a change in PSA levels that signals their cancer has returned, according to new research from Fox Chase Cancer Center.

Austrian researchers receive $7.4 million award to verify new breast cancer pathways

The innovator's award recognises Josef Penninger's work in identifying a key molecular pathway how hormone replacement therapies and contraceptive pills can lead to breast cancer. His team provided the first genetic proof that a protein called RANKL is the master regulator of bone loss, which has contributed to the development of a novel drug already approved for the treatment of osteoporosis and skeletal related events in multiple cancers.
