Anal cancer is a type of cancer that begins when the cells in the anus develop an abnormal mutation. Normal cells grow and divide at a regular rate, but abnormal cells continue to grow and multiply despite the fact that the cells' genes are defective. The accumulated abnormal cells form a tumor, which grows until it threatens nearby normal tissue. Once the tumor has spread, the cancerous cells may separate from the original tumor and may spread to other parts of the body.
Most anal
tumor respond well to combination therapy. Surgery combined with chemotherapy
and radiotherapy provides the best long-term survival rates. Seventy to ninety
percent of patients survive five years after surgery and chemotherapy. If
cancer returns, additional studies may be necessary. While a combination of
these therapies is most effective for patients who have recurrent cancer, it
comes with its own set of side effects. Anal tumor is difficult to diagnose,
but treatment is available and can significantly improve a patient's quality of
life. The worldwide anal
cancer market is likely to be hampered by the negative effects of
chemotherapy medications used in the treatment of anal cancer throughout the
forecast period.
Patients
who are suspicious of anal tumor may undergo an anal pap smear. The process is
similar to that used for a Pap smear. A doctor collects cells from the anal
lining and studies them for abnormalities. If the cells are abnormal, they may
be removed or further tested with an imaging test. Patients with advanced
cancer may require chemotherapy. Anal tumor/cancer treatment may involve
chemotherapy or a combination of both. Additionally, some benign anal
conditions may increase the risk of developing anal cancer. These conditions
are often harmless and are not symptoms of the disease, but may occur because
the anus is infected with cancer cells
The
symptoms of anal tumor are different for different people. Anal tumor usually
recurs within two years of diagnosis. If the disease is diagnosed at an earlier
stage, there's a chance it won't come back. However, recurrences are common in
people who are older
