An increased level of beta-human chorionic gonadotropin may be a sign of a cancer of the uterus, ovary, liver, stomach, pancreas or lung, or gestational trophoblastic disease. Beta-human chorionic gonadotropin may also be produced in response to certain conditions that are not cancer. Also called B-hCG.

Not cancerous. Benign cells are not able to spread like cancer cells.

Bettering the Evaluation and Care of Health

At the beginning of the trial, before treatment is started.

Adjusting rates to take into account how many old or young people are in the population being studied. When rates are age standardised, differences in the rates over time or between geographical areas do not simply reflect variations in the age distribution of the populations. This is important when looking at cancer because it is a disease that predominantly affects the elderly. So if cancer rates are not age standardised, a higher rate in one country is likely to reflect the fact that it has a greater proportion of older people.
