Known as one of the deadliest diseases today, cancer (also referred to as malignant neoplasm) is caused by an uncontrolled growth, invasion and metastasis of oncogenes in the body. The uncontrolled growth of metastatic cells is caused by different factors like infectious agents, radiation and tobacco smoke. Aside from these, abnormalities in the genes can also be due to DNA replication errors, DNA methylation as well as microRNAs.
The diagnosis of the disease commonly requires the histologic analysis of a tissue sample extracted by a pathologist. When it comes to treatments, cancer patients are encouraged to undergo surgeries, radiotherapy and chemotherapy to eliminate the cancer cells. Because of the development of new medical technologies and methods that are used to treat the disease, many patients are now considered as cancer survivors.
Survival of Cancer Patients
When are you considered a cancer survivor? In the past years, physicians consider an individual to be a cancer survivor when the person is diagnosed to be free from the malignancy for at least a year.

Once a patient is diagnosed with the disease, there are treatments that the individual should undergo. One of the advanced treatments for this deadly disease is photodynamic therapy.
Photodynamic therapy involves the use of lasers and photo sensitizers. Other therapies that can be used to treat the disease are hormonal therapy and immunotherapy. Aside from these, outstanding medical centers and hospitals in the world also offer symptom control care to cancer patients.
