Cancer is a class of diseases characterized by out of control cell growth.
Cancer is a class of diseases characterized by out of control cell growth. There are over 100 different types of cancer, and each is classified by the type of cell that is initially affected.Cancer harms the body when damaged cells divide uncontrollably to form lumps or masses of tissue called tumors except in the case of leukemia where cancer prohibits normal blood function by abnormal cell division in the blood stream . Tumors can grow and interfere with the digestive, nervous, and circulatory systems, and they can release hormones that alter body function. Tumors that stay in one spot and demonstrate limited growth are generally considered to be benign.
More dangerous, or malignant, tumors form when two things occur:
a cancerous cell manages to move throughout the body using the blood or lymph systems, destroying healthy tissue in a process called invasion
that cell manages to divide and grow, making new blood vessels to feed itself in a process called angiogenesis.
When a tumor successfully spreads to other parts of the body and grows, invading and destroying other healthy tissues, it is said to have metastasized. This process itself is called metastasis, and the result is a serious condition that is very difficult to treat.
2. Who Gets Cancer
In the United States, half of all men and onethird
of all women will get cancer at some time
in their life. This statistic includes skin cancers,
most of which are easily treated. Millions of
people have cancer today or have had it in the
past. It affects all races and age groups,
although it is more prevalent in the elderly and
in certain geographical region.
Waiting for test results can be difficult for patients and
their caregivers. This includes initial diagnostic tests and
subsequent tests to identify returning or metastasizing
spreading disease. It is important that both you and
your loved one get support from friends and family members
at times like this. Using relaxation techniques to
relieve stress may also be helpful.
You eat pretty well some days and work out most days . But if youre like a lot of men, a trip to the doctor isnt on your to do list. That can be bad if it means you brush off early signs of cancer.
One of the best ways to fight the disease is to catch it in the early stages, when its more treatable. The problem is that the warning signs for many kinds of cancer can seem pretty mild.
Take a look at these 15 signs and symptoms. Some are linked more strongly to cancer than others, but all are worth knowing about and even talking over with your doctor.1. Problems When You Pee
Many men have some problems peeing as they get older, like:
A need to pee more often, especially at night
Dribbling, leaking, or an urgent need to go
Trouble starting to pee, or a weak stream
An enlarged prostate gland usually causes these symptoms, but so can prostate cancer. See your doctor to check on the cause of the problem. He Will give you an exam to look for an enlarged prostate, and he may talk to you about a blood test called a PSA test for prostate cancer.
2. Changes in Your Testicles
If you notice a lump, heaviness, or any other change in your testicle, never delay having it looked at, says Herbert Lepor, MD, urology chairman at New York University Langone Medical Center. Unlike prostate cancer, which grows slowly, testicular cancer can take off overnight. Your doctor will look for any problems with a physical exam, blood tests, and an ultrasound of your scrotum.
3. Blood in Your Pee or Stool
These can be among the first signs of cancer of the bladder, kidneys, or colon. Its a good idea to see your doctor for any bleeding thats not normal, even if you dont have other symptoms, Lepor says. Although youre more likely to have a problem thats not cancer, like hemorrhoids or a urinary infection, its important to find and treat the cause.
4. Types of Cancer
Cancers are often described by the body part that they originated in. However, some body parts contain multiple types of tissue, so for greater precision, cancers are additionally classified by the type of cell that the tumor cells originated from. These types include:
Carcinoma: Cancers derived from epithelial cells. This group includes many of the most common cancers, particularly in older adults. Nearly all cancers developing in the breast, prostate, lung, pancreas, and colon are carcinomas.
Sarcoma: Cancers arising from connective tissue i.e. bone, cartilage, fat, nerve , each of which develop from cells originating in mesenchymal cells outside the bone marrow.
Lymphoma and leukemia: These two classes of cancer arise from cells that make blood. Leukemia is the most common type of cancer in children accounting for about 30%.However, far more adults develop lymphoma and leukemia.
Germ cell tumor: Cancers derived from pluripotent cells, most often presenting in the testicle or the ovary seminoma and dysgerminoma, respectively .
Blastoma: Cancers derived from immature precursor cells or embryonic tissue. Blastomas are more common in children than in older adults.
5. Call Your Doctor About a Cancer If
Cancer and cancer treatments may cause side effects that require immediate attention. However, it is often hard to know when to call the doctor. For example, you may struggle to differentiate between a common cold and a more serious infection. Therefore, it is important to ask your doctor to explain the potential side effects of your specific type of cancer and cancer treatment, as well as the circumstances under which you should call for help.
Some side effects that require immediate attention include infections, deep vein thrombosis a potentially life threatening blood clot , and tumor lysis syndrome a condition that can cause organ failure .
