ScienceDaily (Feb. 25, 2009) - Researchers at Purdue University have precisely measured the impact of a high-fat diet on the spread of cancer, finding that excessive dietary fat caused a 300 percent increase in metastasizing tumor cells in laboratory animals.
Scientists have developed the first "personalised" drug shown to be effective against advanced melanoma, the deadliest type of skin cancer which is on the rise in Britain.
Warnings about the risks of melanoma were heightened this weekend as the fine weather drew thousands to sunbathe outdoors, putting them at increased risk. "Binge tanning", where sunbathers allow their skin to burn in their eagerness to get a tan, is a key cause of the cancer.
Melanoma, which starts as a blemish or change to a mole on the skin, is treatable in its early stages but once it has spread to other organs such as the lungs and liver there are no treatment options. Patients with melanoma that has spread usually die within months
Women who are vitamin D deficient when they are diagnosed with breast cancer are more likely to have their disease spread and are more likely to die than women who have adequate vitamin D levels, new Canadian research says.
The study found that women who were vitamin D deficient were 94 per cent more likely to have their cancer metastasize (spread) and 73 per cent more likely to die.
The research was led by Dr. Pamela Goodwin, a breast cancer researcher at Mount Sinai Hospital in Toronto. The study analyzed blood samples and disease outcome from more than 500 women diagnosed with breast cancer between 1989 and 1995. Women were followed up for an average of 11 years.

Lung cancer and its adversities can be lethal, if remains undiagnosed or left untreated. A multidisciplinary approach can successfully eliminate the cancer from lungs and patient may resume normal life after recovery,

Lung cancer
There are different sizes and stages of lung cancer, which are treated differently. Broadly, specialists categorize various types of lung cancer into two basic forms Non-small cell lung cancer and small cell lung cancer.
The staging of lung cancer helps in deciding the severity of the disease,
course of treatment, and chances of survival. Detection of cancer at an early stage increases the chances of successful treatment and full recovery of the patient. A small legion located in one area is known as the first stage; a little larger tumor is called stage 2; spread within the lungs is called stage 3, and if it spread to other parts then termed as stage 4.

The active compound in marijuana, THC, can slow the growth of lung tumours and reduce the spread of the cancer in mice, a preliminary study reveals.
Human lung cancer tumours grew less than half as fast in mice that received moderate doses of the compound, the researchers reveal. They hope that drugs mimicking the apparent anti-cancer effects of tetrahydrocanabinol (THC) could one day help treat patients. The team strongly discourage people from self-medicating by smoking marijuana, noting that doing so could potentially encourage tumour growth.
ScienceDaily (Feb. 8, 2006) - Vitamin D can inhibit the spread of prostate cancer cells by limiting the activity of two specific enzymes, University of Rochester Medical Center scientists report. \n\nThe finding means that vitamin D could provide beneficial treatment to prostate cancer patients with high levels of the enzymes, the scientists said.\n
"December 17, 2009 (San Antonio) - A new targeted cancer drug has been shown to shrink tumors in women with metastatic breast cancer after an average of seven other drugs, including Herceptin, failed.
The new drug, called T-DM1, combines Herceptin with a potent chemotherapy drug. It's a Trojan horse approach, where Herceptin homes in on cancer cells and delivers the cancer-killing agent directly to its target.
Tumors shrank in one-third of women with metastatic breast cancer given T-DM1, says Ian Krop, MD, of the Dana-Farber Cancer Institute in Boston. In another 12%, tumors stopped growing for at least six months.
The women remained cancer-free for an average of seven months -- results unheard of in patients this sick, he says.
All the women, who had breast tumors for an average of three years, had cancer that had metastasized, or spread to other parts of the body. They had been treated with an average of seven different therapies, including Herceptin, Tykerb, and Xeloda, and each had failed."

A platelet cloak for tumor cells
Blood, January 1, 2005; 105(1): 5 - 6.
Palumbo and colleagues show that platelets and fibrinogen protect metastatic tumor cells from elimination by NK cells, confirming a striking mechanistic link between activation of the blood coagulation system and the spread of tumor metastases
Re-engineering a protein that helps prevent tumours spreading and growing has created a potentially powerful therapy for people with many different types of cancer. In a study published in the first issue of EMBO Molecular Medicine, Canadian researchers modified the tumour inhibiting protein, von Hippel-Lindau (VHL), and demonstrated that it could suppress tumour growth in mice.
Colon cancer has a little complex staging system as the stages advance with the spread of cancerous cells in the colon and other parts surrounding colon. Every professional has a great emphasis on the detection of the disease at an earlier stage because the timely recognition of the cancer accompanies higher chances of recovery and permanent cure.
For several types of cancer, persistently high levels of the soluble factor TGF-beta in the blood after surgery, chemotherapy, or radiation therapy correlate with increased risk of early metastasis and a poor prognosis. Using a mouse model of breast cance
