Cancer, a disease due to abnormal cell growth, is the second largest death cause , after heart disease.
Several, over one hundred types of câncer affects humans.
While science is continuosly searching causes , and treatments for câncer our society still don`t have clear and definite medicines, technologies and instruments to defeat such disease.
Many physical signs and symptoms, such as presence of lumps, abnormal bleeding, prolonged cough, unexplained weight loss, and a change in bowel movements may indicate cancer, but they can also have other causes.
Early detection, through screening, can allow to treat the patient with more possibilities than when the câncer is already spreading in the body.
Such methods are already being utilized in many instances, such as breast and cervical câncer helping reduce its risks of development by early treatment.
For that reason early detection is a major technique to face the challenges of câncer and has to be improved with new methods, instruments and technologies, that can start from genetic research of causes to further prevention techniques including safe lifestyle.
