Information about behaviors, exposures, and other factors that may influence the risk of cancer the genetics of cancer information about genetic changes, how they may be inherited or acquired during a person's life, and how they can increase cancer risk. Although the specific causes of premature labor are not yet known, certain factors may increase a woman's risk of having premature labor however, having a specific risk factor does not mean a woman will experience premature labor. Current diagnosis of alzheimer's disease relies largely on documenting mental decline, at which point, alzheimer's has already caused severe brain damage researchers hope to discover an easy and accurate way to detect alzheimer's before these devastating symptoms begin. Some risk factors may be more powerful than others at certain stages in development, such as peer pressure during the teenage years just as some protective factors, such as a strong parent-child bond, can have a greater impact on reducing risks during the early years.

While women generally enter menopause between the ages of 41 and 55, there are many factors that can interrupt the normal cycle of a woman's reproductive system. It is generally believed that all mental disorders — including clinical depression — are caused by a complex interaction and combination of biological, psychological, and social factors. Some cases are caused by an inherited change in one of three genes, resulting in a type known as early-onset familial alzheimer's disease, or fad for other cases of early-onset alzheimer's, research suggests there may be a genetic component related to factors other than these three genes. Puberty is the process of physical changes through which a child's body matures into an adult body capable of sexual reproductionit is initiated by hormonal signals from the brain to the gonads: the ovaries in a girl, the testes in a boy.
Early menopause refers to cases where onset occurs before age 40 there are several known causes of early menopause, but sometimes the cause is unknown. A risk factor is anything that affects your chance of getting a disease such as cancer different cancers have different risk factors some risk factors, like smoking, can be changed others, like a person's age or family history, can't be changed although certain factors increase a woman's.

Recent research has also helped to change the concept of a risk factor from a fixed, specific circumstance or life stress to a broader, more general phenomenon that may be modifiable, or malleable, and related to a developmental phase (avison, 1992) these findings have led to a shift in risk factor research in both emphasis and complexity. The cause of ms is not known scientists believe ms is triggered by a combination of factors to identify the cause, research is ongoing in areas of immunology (the study of the body's immune system), epidemiology (the study of disease patterns in large groups of people) and genetics.
