Cancer drug - Xeloda

In the news today:

THE makers of a cancer drug used for patients whose disease has spread have asked doctors not to start new patients on the medicine because of a global shortage.

An Adelaide oncologist said yesterday he was about a week away from putting a patient on intravenous chemotherapy instead of the oral medication, Xeloda, which was in short supply.

Dusan Kotasek, based at the Adelaide Cancer Centre, said if supplies of Xeloda ran out, it would be a "very substantial and dramatic challenge to the day-treatment facilities", where patients would need to go for intravenous therapy, instead of taking capsules at home.

Drug company Roche said about 1780 Australians were on Xeloda each month, principally for metastatic breast or colorectal cancer.

In a letter to doctors and pharmacists, Roche says it has been dealing with supply issues for some months.

"Unfortunately, due to increasing demand at this time of year, we now need to put additional measures in place to ensure that patients who most need Xeloda have continued access to it," the letter says.

"We ask that oncologists consider, where alternative therapies are available, not commencing new patients in metropolitan areas on Xeloda."

Dr Kotasek said Xeloda was the oral equivalent of fluorouracil (5-FU) and was especially useful for patients in regional and remote areas, who could avoid travelling to access intravenous chemotherapy.

"There have been a number of drug shortages for one reason or another over the years," he said. "This is just another example where a single supplier reduces the supply and there's worldwide consequences."

Pharmacy Guild SA president Ian Todd said he called Roche last week for some Xeloda for a customer. He was told he could have some but it was not being released generally in case pharmacies started stockpiling.

A Roche spokesman said the "additional measures" were because of an increased demand for Xeloda in December and January.

Kate Jackson Breast Cancer a flash back

THE MOST MOMENTOUS CHANGE IN Kate Jackson's life began early one morning in January 1987, during her fourth season on the hit TV series Scarecrow and Mrs. King. After a phone call informed her that the show's taping was canceled because costar Bruce Boxleitner had the flu, Jackson went back to sleep. When she woke several hours later, "It was out of the blue, but perfectly clear," she recalls. "I sat up in bed and literally said, 'You have to have a mammogram.' " She did, and two days later a biopsy confirmed her vague fears: A minute growth found in her left breast was determined to be malignant. "I was forced to face, squared up, my own mortality," says Jackson. "I had to decide whether I wanted to live or to die. And if you choose life, as I did, it's never the same." For three TV seasons 16 years ago, she was famous as Sabrina Duncan, a girl-next-door gone glamorous and the character critics dubbed the brainiest o

"Hard nipples" - areola or nipple skin

Someone once wrote"... when i get really cold, or get goosebumbs all over my body, the whole things really scrunch up, like, my entire areola scrunches itself up into a wrinkled little mound. it looks really weird and ugly, and i haven't ever seen other people's breasts do it. what is wrong with my areola/nipples??" The answer: Well nothing is wrong. This is what my areola does too. It's a normal reaction to the coldness or to irritation / stimulation. The little muscles in the areola do a similar goosebump thing as your other skin can do. People often call this phenomenon "hard nipples". Also note that skin on areola has less feeling or sensation to it than other areas of your body. If the areola was very sensitive, then breastfeeding would probably be quite uncomfortable because the baby pulls and tugs it! The nipples are sensitive but the sensitivity changes with hormonal changes, such as occur at mestrual cycle or pregnancy. Also this v

The four stages of breast development

Stage 4 shows fully mature breasts. (Illustration by GGS Information Services.) period begins. Usually these signs are accompanied by the appearance of pubic hair and hair under the arms. Once ovulation and menstruation begin, the maturing of the breasts begins with the formation of secretory glands at the end of the milk ducts. The breasts and duct system continue to grow and mature with the development of many glands and lobules. The rate at which breasts grow varies significantly and is different for each young woman. Breast development occurs in five stages: Stage One: In preadolescence, the breasts are flat and only the tip of the nipple is raised. Stage Two: Buds appear, breast and nipple are raised, fat tissue begins to form and the areola (dark area of skin that surrounds
