TUESDAY, June 24 (HealthDay News) U.S. researchers say they've spotted an important factor in the development of B-cell lymphomas, one of the fastest growing forms of cancer.

In experiments with mice, researchers at the National Jewish Medical and Research Center, Denver, found that the B-cell receptor on the surface of B-cells can cooperate with the MYC oncogene to accelerate the development of lymphomas. They also found that disrupting signals from the B-cell receptor can inhibit tumor growth.

MONDAY, June 23 (HealthDay News) -- Low socioeconomic status increases a cancer patient's risk of dying, say U.S. researchers who analyzed data on almost 14,000 breast, prostate and colorectal patients in seven states.

The study found that cancer patients with low socioeconomic status had more advanced cancers at time of diagnosis, received less aggressive treatment, and had a higher risk of dying within five years of diagnosis.

For example:

MONDAY, June 23 (HealthDay News) -- A powerful weapon against cancer might also boost stroke patients' survival, new research suggests.

Gleevec, long hailed as a "wonder drug" against cancers such as chronic myelogenous leukemia (CML), will be tested to see if it can boost the effectiveness and limit the side effects of the clot-dissolving drug tissue plasminogen activator (tPA), an international team of researchers say.

MONDAY, June 23 (HealthDay News) -- U.S. researchers boosted the level of early-stage ovarian cancer detection by 20 percent through use of a blood test to detect a tumor marker as well as a woman's report of new-onset symptoms.

Using either test alone only uncovered about 60 percent of early-stage ovarian cancers in a high-risk group of women, while the two techniques together found 80 percent of early-stage tumors, according to finding published Monday in the online version of the journal Cancer.

Hi

We just noticed a small blackish brown mole on our toddlers thigh that has appeared out of nowhere. It is dark brown in color and is quite small but noticeable. It has not changed in size or color or consistency since it sprouted but it hasn't been that long. It wasn't there a few weeks ago - this is brand new.

Does anyone know why this would happen? Is it something that needs to be seen by a doctor or is this common?

She has very fair skin and wears a factor 50 sunblock at all times and has no other moles or freckles.

Thanks
