Next to skin cancer, the most prevalent form of cancer in women is breast cancer. According to the American Cancer Society (ACS) the chance of developing breast cancer over a lifetime is less than 1 in 8. The most extensively used breast screening technique is an x-ray exam of the breast or mammogram. The ACS reports that organized mammographic screening reduces breast cancer mortality by more than 60%, and recommends yearly mammograms starting at age 40. Women with a strong family history of breast cancer, or who have other risk factors, are advised to begin routine screening earlier.

Cell Phones: Where’s my earpiece?

Numerous case-control studies have examined the possible correlation between long term use of cell phones (specifically, the electromagnetic radiation emitted by cell phones) and the incidence of brain tumors.
In the fall of 2009, the World Health Organization published a 10 year study which examined the cell phone habits of more than 120,000 people in 13 countries.

Human Papilloma Virus (HPV) is a family of small, non-enveloped DNA viruses which infect epithelial cells, and of which there are over 100 subtypes. HPV is divided into two major categories, high risk types which includes types 16, 18, 31. 33, 35. 39, 45, and low risk types 6 and 11. HPV 16 is implicated in over 90% of cervical cancers and shown to be a causal factor in the development of the disease. HPV produces two oncoproteins, E6 and E7, which inactivate the cellular tumor suppressor proteins, p53 and pRB respectively. This allows it to disable two of the More >
Hildegard’s Dilemma
Oct 14th
Hildegard von Bingen, a 12th century nun was celebrated for her intellect, writings, and notably for her extraordinary visions – also known as migraine auras. Ask any migraineur about the scintillating scotomas preceding a migraine, and you’re likely to receive a flinching look in return. Migraines with aura are chronic headaches characterized by specific neurological symptoms – visual disturbances, nausea, sensitivity to light, sounds, smells, and usually accompanied with an unilateral blinding headache—the hallmark TKO of migraines.
