Why is your big toenail black?

By definition, your toenails, as well as your hair, and as opposed to your skin - is always dead.

What happens if it gets black is that you've had a bleed under the nail, in the nail bed.

That kind of thing will often - but not always - disturb the growth zone of the nail somewhere behing the cuticle.

When that happens, the nail will no longer be able to grow as a continuous unit. There'll be a stop in the growth, a break in the nail, and then there'll be a new nail. As the new nail grows the old will be pushed ahead and eventually fall off.

What is metastatic renal cancer?

The most common form of kidney cancer is called renal cell carcinoma. The kidneys are organs that work with the urinary tract to create urine by removing extra water and waste from the body. The kidneys are located in the lower part of the back on either side of the spine. Kidney cancer can spread outside of the kidneys to the liver, lymph nodes, and lungs. Males are more likely to develop kidney cancer in the United States, with approximately 20,000 men and 12,000 women being diagnosed with kidney cancer annually.

Risk Factors

Kidney cancer develops primarily in individuals over 40 years. Doctors do not know the exact causes of kidney cancer, but there are certain associated risk factors. Individuals who smoke, are obese, or have high blood pressure have an increased risk of developing kidney cancer. People who are on dialysis for an extended period of time are at risk of cancer forming in the kidneys. Another risk factor involves certain occupations. Individuals working around certain chemicals may also be at risk.

Symptoms

Common symptoms associated with kidney cancer include blood in the urine, which makes the urine appear rusty. Pain in the side or lower back that does not go away is another symptom of kidney cancer. A lump in the side or abdomen, fever, weight loss, and fatigue are also associated symptoms. However, it is important to note that these symptoms can appear when cancer is not present. A cyst or infection in the kidneys can cause similar symptoms.

Diagnosis and Treatment

A personal suspected of having kidney cancer may undergo a urine analysis to check for blood in the urine. Blood tests are performed to determine how effective the kidneys are working. A CT scan or ultra sound is used to determine if a tumor is present. Once the tumor is found, the doctor may perform a biopsy to determine if cancer cells are present. A doctor uses the information found to determine whether to remove all or part of the diseased kidney. People with kidney cancer may also need to undergo radiation therapy or chemotherapy.

What is the life expectancy of a heart problem patient?

I am a TOTAL layman, but after having done extensive research here on line to answer this question about my 77 year old dad, what I've been able to discover is that there IS NO ANSWER... that the life expectancy for a patient with end stage congestive heart failure is completely unique to that particular individual. Their age, level of strength, degree of heart damage and a mulititude of other factors all play a part in the eventuality. The closest that I could find to narrowing this down is that on the high side of the factors, a person might expect as much as five years. On the lowest possible scale of factors, several weeks to months.

How fast does colon cancer kill you?

Colorectal cancer is the third most common cancer in men and women in the U.S. When it's caught in its early stages, it's easily treated and often cured. But because it is usually not discovered early, it is the second leading cause of cancer deaths in the U.S. The exact cause is unknown, but most cases begin as polyps, which are small growths inside the colon or rectum. Colon polyps are very common, and most of them do not turn into cancer. Most polyps are easily found with fairly simple screening tests. Screening tests are tests that look for a certain disease or condition before any symptoms appear. In the case of colon cancer, screening tests can find evidence of polyps in the intestine. Sometimes the doctor can remove any polyps that are found at the same time.

You are more likely to get colorectal cancer if you eat a high-fat diet, smoke, or have a history of this type of cancer in your family. However, most people who get colorectal cancer have none of these things in their background. Other, less common symptoms of early-stage colorectal cancer include fatigue and unexplained weight loss.

If caught in time the chances of beating colon cancer is very high.
