Lasers are used to treat cancer in several different ways. Their high-intensity light can be used to shrink or destroy tumors or precancerous growths. Lasers are most commonly used to treat superficial cancers (cancers on the surface of the body or the lining of internal organs) such as basal-cell skin cancer and the very early stages of some cancers, such as cervical, penile, vaginal, vulvar ...
When hormonal treatment is appropriate, doctors may choose to start treatment early, right after the diagnosis is made, or wait until the cancer has begun to grow. For men with advanced prostate cancer early hormonal treatment probably lowers the risk of dying from any cause, including dying from prostate cancer without severely affecting ...
Lowering androgen levels or stopping them from getting into prostate cancer cells often makes prostate cancer shrink or grow more slowly for a time. However, this treatment needs to be combined with radiation therapy (RT) [ 8 ] because ADT itself does not eradicate the cancer ; it just decreases its aggressiveness.
Prostate cancer is the most diagnosed cancer in men in over half of the world's countries, and the leading cause of cancer death in men in around a quarter of countries. [91] Prostate cancer is rare in those under 40 years old, [92] and most cases occur in those over 60 years, [2] with the average person diagnosed at 67. [93]
Prostate cancer screening is the screening process used to detect undiagnosed prostate cancer in men without signs or symptoms. [1] [2] When abnormal prostate tissue or cancer is found early, it may be easier to treat and cure, but it is unclear if early detection reduces mortality rates.
In some cancer types, prolongation of the fraction schedule over too long can allow for the tumor to begin repopulating, and for these tumor types, including head-and-neck and cervical squamous cell cancers, radiation treatment is preferably completed within a certain amount of time.
Multimodal cancer therapy, often referred to simply as multimodal therapy or multimodal cancer care, is an approach for treatment of cancer that combines radiation and chemotherapy [1] or other multiple therapeutic modalities.
Cancer treatments are a wide range of treatments available for the many different types of cancer, with each cancer type needing its own specific treatment. [1] Treatments can include surgery, chemotherapy, radiation therapy, hormonal therapy, targeted therapy including small-molecule drugs or monoclonal antibodies, [2] and PARP inhibitors such as olaparib.
