LATEST RESEARCH ABOUT ONCOLOGY:

Cancer is now recognized as a genetic disorder arising from errors in cell replication, arising from various factors, such as environmental damage by the action of chemical agents and radiation or even lifestyle, leading to uncontrolled cell reproduction. Here we see the latest Cancer Research

INTRODUCCION

The Journal of the American Medical Association.

Multivitamins may reduce cancer risk

Suggest that taking a daily multivitamin may reduce the risk of cancer of older men.

A randomized trial of 14,000 men after 50 years or more for an average of 11 years.

They found that those taking a daily multivitamin supplement were 8 percent less likely to be diagnosed with cancer than those taking a placebo.

The building blocks of an emerging science that is enabling cancer researchers to break new ground in the way we treat disease.

nanotechnology, researchers in the laboratory

seek to reduce side effects and improve the effectiveness of cancer drugs.

Scientists giving greater control over the selection of treatments.

Ovarian Cancer Screenings Are Not Effective

According to a study published last year in the journal of the American medical society

78.216 American women between the ages of 55 to 74 years

of

half of them have been selected to continue a control that had a duration of 11 to 13 years

while the other half not.

The screening consisted

ultrasound exams

blood tests

andfor elevated Levels of a substance called CA-125

Which can be a sign of ovarian cancer

Result There was no advantage to screening:

the death rate from ovarian cancer was the same in the two groups.

Genes Now They Can not Tell Secrets Doctors Utter

Dr. Arul Chinnaiyan stared at a printout of gene sequences from a man with cancer, a subject in one of his studies

There, Along with the man's cancer genes, was something unexpected - genes of the virus causes AIDS That ...

In laboratories around the world,

using genetic tools Researchers are ever more sophisticated That to peer into the DNA of cells are increasingly finding things They Were not looking for

Information That Could make a big difference to an anonymous donor.

Including

DENSE BREAST TISSUE DOES NOT ADD CANCER DEATH RISK, STUDY

SHOWS USA TODAY

Studies have long Shown an Increased risk of breast cancer in women Whose breasts are considered "dense," or less fatty.

The women with less dense breasts Were more likely to die of Their Breast Cancers

New research showing patients with breast cancer That dense breasts Were no more likely to die than other patients.

The study included more than 9,000 women

Stem Cell Findings Point Toward New cancer

treatments

Strategies can be designed to kill

Everything has a weakness, with all modern molecular techniques and

modern approaches we have, we can kill

specific cells within tumors are responsible for its continued growth

The cancers are fueled by stem cells that

chemotherapy drugs do not kill

When these tagged cells are divided, all daughter cells were stained similarly

This allowed the researchers to determine if

any old cell into a tumor may continue to fuel

growth or only a subset of cells is responsible.

molecular tricks allow scientists to make certain tumor cells brightly

Next, the scientists Treated the mice with a chemotherapy drug Rapidly dividing That Kills tumor cells.

the new cells were all descendants of the green-glowing cells That Were not killed by the drug.

When the tumors grew back, do as glioblastomas

Generally, the scientists used other chemical tricks to seeThat

The next step was to see what would happen if the cancer stem cells Were wiped out

Were wiped out, to test That was possible Because of the way the mice Were genetically constructed

 Without the stem cells, the tumors never grew as large and the animals lived longer.

The scientists Concluded

That When other cancer cells stop dividing Within the mass.

That They Had Destroyed the wellspring of the tumor cells renew

Today, only kill cancer medications Generally Rapidly dividing cells

Biotech companies and academics are working on the problem.

scientists do not yet know enough about cancer stem cells to target them

Overall, scientists are finding That grotesque caricatures Cancers are of normal body tissues

said John E.Dick, senior scientist at Toronto's Princess Margaret Cancer Center

Whose work in the 1990s provided early evidence for stem cells in leukemia

Just as healthy tissues Contain a mix of cells - - ones That are dividing

, ones That have taken on distinct identities, and Stem Cells That Periodically replenish the tissue

- so, too, do cancers.And just as usual tissue growth Involves a

complicated dance of chemical messages among cells, so, too, might the growth of cancers.

That complexity makes the prospect of devising new therapies seem daunting, Dick said

But, I added, it opens up a whole new menu of Strategies That scientists can try.
