The human genome is the complete collection of over three billion bases in each of our cells. Cancers accumulate multiple changes, or mutations, in their DNA that contribute to the disease by changing how cells behave. For instance, cancers need nutrients to grow. Very often, they get these nutrients by producing signals that encourage new blood vessel formation. Finding the mutations that lead to cancer is very difficult. For one thing, even for cancers that affect the same tissue and look similar, the mutations can be very different. Also, one of the hallmarks of cancer is an increased rate of More >

Unlike many mental disorders, schizophrenia usually strikes much later in life (usually in mid to late adolescence) and so parents and patients alike may be unaware that there is a potential problem. In many places adequate access to proper mental-healthcare is lacking, so even when a diagnosis is possible, treatment may not be.
