Brain intrepid women reveals key phobias (CBC)

The literally intrepid woman - case thus rendered after brain damage - helped scientists to confirm that a part of the structure of the brain regulating emotions is key to human and animal phobias.

The mother of 44 three referred in the journal Current Biology as MS, with a rare emotional disorder due to a genetic disease called fat proteinosis that left holes where the amygdala - threatening brain detector - would normally resident.

The patient felt excitement, but never fear in a series of threatening scenarios monitored by researchers at the University of Iowa, led by Justin Feinstein, a clinical Neuropsychologist.

American woman took her pet store to interact with snakes and spiders, where it has been reported to have exclaimed, "This is so cool!" while rubbing the snake scales and touching his language.

Pet Shop employees had warned about the danger of exotic animals. Previously, the patient also admitted that she hated snakes and spiders. During testing, however, it should be lured away to reach toward a Tarantula.

Requested by researchers to evaluate its fear of 0 to 10, it never exceeded two.

Led by scientists in a "haunted house", Ms approached staff eagerly disguised as monsters, even amazing an interpreter hidden by attacked at the head, thinking that she was "curious" to know how he would feel the mask.

While she viewed as the experience of being "very exciting and fun", comparing it to the feeling of a roller-coaster ride, rating of fear was zero.

Horror like The Blair Witch Project and the shining path also recorded minimum readings for fear of it.

Scientists are studying MS for more than two decades, with several articles on his fear-related anomalies.

While she recalled feeling fear as a child, after a meeting with a snarling Doberman pinscher scary that it forced, she could not recall fearing anything in adulthood.

Overnight in 1995, a strange man fried to a park bench and pressed a knife to her throat, threatens to cut.

"If you're going to kill me, you'll pass by the angels of my God," she replied, he quietly watching. Then, she left and returned to the Park the next day.

Scientists seek to conduct DM coach react differently in such dangerous situations.

"It's quite remarkable that she is still alive," said Feinstein, noting that she presented itself unduly dangerous scenarios because of his inability to deal with fear.

Researchers believe that understand how works of spirit of the DM can assist with the discovery of treatments for PTSD.

Mammography can help women aged 30-39 - study (food)

Women aged 30-39 years, at the risk of breast cancer can benefit from mammography screening, suggests a new study presented Friday at the Symposium 33rd Annual San Antonio Breast which is held in San Antonio, Texas.

Study sponsored by Kaplan Cancer Research Fund and managed by kaplan, h. g., and his colleagues at health-stat Consulting Inc. in Seattle, WA and the Swedish national cancer Institute to mammography screening tend to find at an early stage breast cancer and has resulted in improved disease-free survival.

Researchers conducted a study cohort all cancer patient protection breast woman aged 21-39 in a community centre, the disease has been confirmed biopsy phase 0 - IV from 1990 to 2008.

For the study, the researchers grouped patients based on how the disease has been detected either by patients, physicians or mammography screening.

Ages 21 to 39 women accounted for 7% of total breast cancer cases. The majority (81%) cases were first by the patients themselves, 7% by doctors and 12% by mammography screening.

Mammography screening most cases detected in the 30 to 34 year age group (26%) and 35-39 years-group of old age (65%).  Eighty-one percent of the cases initially detected by patients or doctors were visible on subsequent mammography.

Researchers have discovered screening mammography has concluded more cases of breast cancer stage 0 only manually, i.e. by patients or doctors, 31 per cent compared to 2.5%. The Group of patients whose breast cancer was first found by mammography has a better free disease of survival.

Age at diagnosis and have a first-degree relative breast cancer have been associated with the detection of mammography.

Researchers concluded "detection of mammography in 20-39 years patient suffering from cancer is associated with the age of 30 > and presence of a first-degree relative affected BC." Survival sickness is significantly better in the mammography group detected in large part due to low stage at the time of diagnosis. »

"These results indicate mammography may be a reasonable option for the detection of high-risk 30-39 year-old women."

False positive diagnosis linked to an increased risk of breast cancer

Another study presented at the same Conference suggests that false positives mammograms may increase the risk of cancer during the 2 years of false positive diagnosis.

The Danish study 60,000 involved women who participate in Copenhagen mammography program invited women aged 50-69 years to get a mammogram every two years.

Women who had a false positive diagnosis were more likely to develop breast cancer before they received the next screening mammography and were more likely to be diagnosed with cancer of breast cancer in the next 17 years, compared to those without false positives, the study revealed from 33% to 73%.

My von Eular-Helpin, Dr.., Professor of public health at the University of Copenhagen, co-author of the study, said WebMD the overall risk was low, only 22 of 5080 that women had finished by be diagnosed a false-positive breast cancer.

EULAR-Helpin was cited as WEBMD some benign lesions may become malignant after a diagnosis of false positives.

Women who have falsely diagnosed breast cancer were subjected to other procedures for invasive diagnosis as biopsy, which in itself can cause harm to breast tissue.

Radiation used in mammography is an agent of cancer

Cervical cancer used today is already known to increase the risk of cancer.

Mr. Samuel s. Epstein, Emeritus Professor of environmental and medicine of work at the school of public health at the University of Illinois, says on its website preventcancer.com postmenopausal women who undergo an annual screening for a period of ten years would receive approximately 10 rads of each breast radiation exposure.

According to Mr. Epstein, each rad premenstrual results for cancer in every 100 women syndrome. A woman with exposure to 10 rads or receptor 10 in 10-year projections have a risk of 10 per cent of the development of cancer of the breast, or 10% of women develop the disease.

The risk of breast cancer with mammography is four times higher among women that A - T gene. Breast radiation-induced cancer represents 20 percent of all breast cancers each year to the United States.
