It is a malignant tumor that develops in the prostate gland. It consists of an uncontrolled growth of prostate cells. This means, among other things, that the prostate, because of its location, press on the bladder and urethra by preventing the normal urine output.

Most prostate cancers grow very slowly, although some do it quickly, they can even spread.

The prostate is a glandular organ, the size of a walnut, found in men and located around the bladder neck and part of the urethra, in front of the rectum. Secretes fluid, white and viscous, which is mixed with sperm at the time of ejaculation.

There are lymph vessels surrounding the prostate and that lead to pelvic lymph nodes.

When a prostate cancer, there is the possibility that cancer cells spreading through lymphatic vessels and affect the lymph and from there to anywhere on the body.

Perhaps are seldom heard or read this information but here’s something they can serve.

Interocular melanoma is a disease in which cells form malignant (cancer) in the tissues of the eye.

Interocular melanoma begins in the middle of the three layers of the eye wall. The outer layer includes the white sclera (the “white of the eye”) and the clear cornea at the front of the eye. The inner layer has a lining of nerve tissue called the retina, which senses light and sends images along the optic nerve to the brain.

The middle layer, where interocular melanoma forms, is called the uvea or uveal tract consists of three parts: Iris, ciliary body and choroid.

The age and sun exposure may increase the risk of interocular melanoma.

Anything that increases the risk of contracting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer, not having risk factors does not mean that you will not get cancer. People who think they may be at risk should discuss this with your doctor. Among the risk factors for interocular melanoma include the following:

* Older age.
* Being white skin.
* Have fair skin or blue or green eyes.
* Power tan.

Possible signs of interocular melanoma include having a dark spot on the iris or blurred vision.

Interocular melanoma may not cause early symptoms. Sometimes this is determined during a routine eye exam when the doctor dilates the pupil and examining the eye. The following symptoms may be caused by interocular melanoma or other conditions. Call your doctor if any of the following problems:

* A dark spot in the iris.
* Blurred vision.
* Change in the shape of the pupil.
* A change in vision.

Glaucoma may develop if the tumor causes the retina to separate from the eye. If this happens, may have no symptoms or symptoms may include:

* Pain in the eye.
* Blurred vision.
* Irritated.
* Nausea.

Tumor ocular choroids malignant melanoma, malignant melanoma of the eye Ocular Melanoma

Definition:

Cancer is cancer that occurs in various parts of the eye.
Causes and risk factors:

Melanoma is a very aggressive form of cancer that can spread rapidly.

Melanoma of the eye can affect several parts of the body, such as:

* The choroid
* The cilia body
* Iris

The choroid layer is the most likely location of melanoma in the eye.

The cancer may only be in the eye or it may spread (metastasize) to another location in the body. Melanoma can also begin on the skin or other organs in the body and spread to the eye.

Melanoma is the type most common eye tumor in adults, yet the primary melanoma of the eye is rare.

A major risk factor is excessive exposure to sunlight. The occurrence of melanoma has greatly increased in recent decades, resulting most commonly affected people with blue eyes and fair skin.

Rheumatic heart disease is caused by damage to the heart valves and myocardium resulting from inflammation and scar deformation caused by rheumatic fever, a disease which in turn is caused by streptococci and usually manifests as croup or tonsillitis ( “angina”) in children. Rheumatic fever primarily affects children in developing countries, especially where poverty is widespread. Worldwide, nearly 2% of deaths from cardiovascular disease are related to rheumatic heart disease, while 42% are associated with ischemic heart disease and 34% with cerebrovascular disease.

Symptoms of rheumatic heart disease

* Symptoms of rheumatic heart disease include shortness of breath, fatigue, irregular heartbeat, chest pain and fainting.
* The symptoms of rheumatic fever include fever, joint pain and swelling, abdominal cramps and vomiting.

Treatment of rheumatic heart disease

* Prompt treatment of strep throat can prevent the onset of rheumatic fever. The prolonged and regular treatment with penicillin can prevent repeat attacks of rheumatic fever, rheumatic heart disease cause and stop the disease progression in patients whose heart valves are already damaged.

Cardiovascular disease (CVD),  the heart and blood vessels, are:

* Coronary heart disease – disease of blood vessels that supply the heart muscle (myocardium);
* Cerebrovascular disease – disease of blood vessels supplying the brain;
* Peripheral arterial disease – disease of blood vessels supplying the arms and legs
* Rheumatic heart disease – damage to the heart and heart valves due to rheumatic fever, a disease caused by streptococcal bacteria
* Congenital heart disease – heart defects present at birth, and
* Deep vein thrombosis and pulmonary embolism – a blood clot (thrombus) in the veins of the legs, which can break off (embolus) and lodge in the heart and lungs.

Heart attacks and strokes (CVA) are usually acute events and are mainly due to blockage that prevents blood from flowing to the heart or brain. The most common cause is the formation of fatty deposits on the walls of blood vessels supplying the heart or brain. Strokes can also be caused by bleeding from the cerebral vessels or blood clots.
Major risk factors

* The causes of CVD are well established and well known. The most important causes of heart disease and stroke are called “modifiable risk factors” unhealthy diet, physical inactivity and consumption of snuff.
* The effects of unhealthy diet and physical inactivity may appear as “intermediate risk factors”: increases in blood pressure and sugar and blood lipids, overweight and obesity.
* The major modifiable risk factors are responsible for approximately 80% of cases of coronary heart disease and cerebrovascular disease.
* There are also a number of underlying determinants of chronic diseases, ie “the causes of the causes”, which are a reflection of the major forces driving social, economic and cultural rights: globalization, urbanization and aging of the population. Other determinants of CVD are poverty and stress.

Having hepatitis or cirrhosis can affect the risk of primary liver cancer in adults.

Anything that increases the risk of a disease is called a risk factor. Having a risk factor does not mean that you will suffer from cancer have no risk factors does not mean they do not suffer from cancer. People who think they are at risk should discuss this with your doctor. Possible risk factors for primary liver cancer in adults are:

* Having hepatitis B or hepatitis C.
* Having a close relative with both hepatitis and liver cancer.
* Suffering from cirrhosis.
* Eating food contaminated with aflatoxin (poison from a fungus that can grow in foods such as grains and nuts, which are not stored properly).

Possible signs of primary liver cancer in adults include a lump or pain on the right side.

These symptoms may be caused by swelling of the liver. These and other symptoms may be caused by primary liver cancer in adults or other conditions. Call your doctor if any of the following problems:

* A hard mass in the right hand side just below the rib cage.
* Discomfort in the upper abdomen on the right.
* Pain around the right shoulder blade.
* Jaundice (yellowing of the skin and whites of the eyes).
* Unusual tiredness.
* Nausea.
* Loss of appetite.

To detect (find) and diagnose primary liver cancer in adults, tests are used to examine the liver and the blood.

You can use the following tests and procedures:

* Physical exam and history: An exam of the body to check general health and identify any signs of illness such as lumps or anything else that seems unusual. Also recorded data on patient’s health habits and past illnesses and treatments.
* Serum tumor marker test: A procedure which checks a blood sample to measure the amounts of certain substances released into it by the organs, tissues or tumor cells of the body. Certain substances are linked to specific types of cancer when found in high concentrations in the blood. These are called tumor markers. An increase in the concentration of alpha-fetoprotein (AFP) in the blood may be a sign of liver cancer. Other cancers and certain noncancerous conditions, such as cirrhosis and hepatitis, may also increase AFP levels.
* Complete blood count (CBC): A procedure in which a sample of blood and checked for the following:
o The number of red cells, white cells and platelets.
o The amount of hemoglobin (the protein that carries oxygen) in red blood cells.
or that portion of the blood sample made up of red blood cells.
* Laparoscopy: A surgical procedure to study the organs inside the abdomen to detect signs of disease. Incisions (cuts) are small in the abdominal wall and a laparoscope (a thin, lighted tube) in one of the incisions. It may introduce other instruments through the same or other incisions to perform procedures such as removing organs or taking tissue samples for biopsy.
* Biopsy: The removal of cells or tissue for a pathologist to observe in the microscope to check for signs of cancer. The sample can be taken with a fine needle is inserted into the liver during an x-ray or ultrasound. This is called a biopsy, fine needle aspiration (FNA). The biopsy can be performed during periscope.
* CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body from different angles. The pictures are made by a computer linked to a x-ray machine May be injected or given to drink a dye to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography or CT scan.
* MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves and a computer to create detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI).
* Ultrasound: A procedure in which sound waves are bounced high energy in internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram. The picture can be printed and watch later.

The liver, the largest organ of the human body without the skin, located below the ribs on right side of the abdomen.

Its main functions include filtering the blood and the elimination of toxic wastes and the production of enzymes that help digest food, converting them into substances needed for the proper functioning of the body. Some nutrients have to be chemically altered (metabolized) in the liver before the rest of the body can use as an energy source. The liver produces some of the clotting factors that prevent the blood is too thin and also secretes bile to the intestine to help absorb nutrients.

The liver is divided into three lobes, the right, the left and a smaller one called square, which in turn are subdivided into segments. Unlike most other organs of the body receives blood from two sources. The hepatic artery supplies the liver with blood rich in oxygen while the portal vein carries nutrient-rich blood from the intestines. All blood from the digestive tract through the liver before it reaches the rest of the body, making it a sort of ‘office’ from the outside world.
