Cancer screening method should be changed

Cervical cancer screening intervals could be extended to five years for women aged 30 and over if the primary screening method was human papillomavirus testing.



Tumour suppressor gene can determine cancer susceptibility

A new study demonstrates that even subtle changes in expression of the PTEN tumour suppressor gene can significantly increase cancer susceptibility in specific tissues.



Supplements may reduce breast cancer risk

Vitamins and calcium supplements appear to reduce the risk of breast cancer. Calcium supplements are acting to enhance DNA repair capacity, a complex biological process involving more than 200 proteins that, if disrupted, can lead to cancer.



Lung cancer development in never-smokers

A five-centre collaborative study that scanned the genomes of thousands of "never smokers" diagnosed with lung cancer as well as healthy never smokers has found a gene they say could be responsible.



Cancer reduction of fruit, vegetables weak

An analysis by researchers of over eight years of dietary data from more than 400,000 people has found that the relationship between high consumption of fruits and vegetables and a reduced risk of cancer is not as strong as commonly thought.



Chip checks for oral cancer

The gentle touch of a lesion on the tongue or cheek with a brush can help detect oral cancer with success rates comparable to more invasive techniques, according to preliminary studies.



Vascular disease linked to cancer

Researchers have discovered how a genetic disease known mainly for its life-threatening tumours also can cause sudden death from cardiovascular disease in children, and are mounting a clinical trial to develop treatments for the problem.



Blocking cancer in its path

Researchers have discovered that a key cellular defect that disturbs the production of proteins in human cells can lead to cancer susceptibility.



New cancer drug screening technique

Scientists have developed a laboratory technique that more closely simulates the real-world conditions in which tumour cells mingle with the body's normal cells.



Nanoparticles target and kill cancer cells

Another weapon in the arsenal against cancer: Nanoparticles that identify, target and kill specific cancer cells while leaving healthy cells alone.



Novel approach to prostate cancer treatment

Researchers in Canada have detected a novel oncolytic viral therapy against prostate cancer with use of a virus called the reovirus, according to study results.



Cancer mortality on the decline

A new study finds progress in reducing cancer death rates is evident whether measured against baseline rates in 1970 or in 1990.



Papaya extract thwarts growth of cancer cells

The humble papaya is gaining credibility in Western medicine for anticancer powers that folk cultures have recognised for generations.



Oestrogen and breast cancer

A new study is providing insight into how oestrogen fuels many breast cancers, and researchers say the findings could lead to new cancer-fighting drugs.



Testosterone deficiency affects male cancer survivors

A new study has found that many male cancer survivors who develop testosterone deficiency after receiving chemotherapy or radiation therapy have an impaired quality of life and reduced energy levels.



Switch turns on the spread of cancer

Researchers describe the discovery of a specific protein called disabled-2 (Dab2) that switches on the process that releases cancer cells from the original tumour and allows the cells to spread and develop into new tumours in other parts of the body.



Rice physicists kill cancer with nanobubbles

Using lasers and nanoparticles, scientists have discovered a new technique for singling out individual diseased cells and destroying them with tiny explosions.



Loss of gene function increases cancer aggression

Prostate cancer cells are more likely to spread to other parts of the body if a specific gene quits functioning normally, according to new data from researchers.



New computational tool for cancer treatment

Researchers developed an approach for creating new IDO inhibitors by computer-assisted structure-based drug design.



Pomegranates may prevent breast cancer

Eating fruit, such as pomegranates, that contain anti-aromatase phytochemicals reduces the incidence of hormone-dependent breast cancer, according to results of a study.
