Metastatic cancers are the cancers that are characterized by their origin. These cancers, even after spreading to another organ, are still identified by the name of the organ they started from. For instance, if lung cancer affects another organ, say the liver, it will be called metastatic lung cancer and not liver cancer. It should be noted that metastatic cancer is not the same as second primary cancer. The survival rate of metastatic lung cancer is different from that of the second primary cancer. Abnormal cells in a new organ are part of metastases only when the cells show similarity to primary cancer, whereas second primary cancer involves the new growth of abnormal cells which are not similar to cancer cells belonging to any other part of the body. The latter kind of cancer is also rare. Some of the organs most commonly affected in metastatic lung cancer include the lymph nodes, brain, liver, adrenal glands, and bones. Although not completely impossible, but, in rare cases, it may also spread to the stomach, intestines, pancreas, and kidneys. Metastatic lung cancer survival rate indicates the rate of people who are alive after a specific period of time following the diagnosis. Five years is the time period that is taken as the base to calculate survival rate.

Lung cancer is a type of cancer that originates in the lungs and is characterized by the spread of abnormal cells that do not stop reproducing. There are two major kinds of lung cancer, non small-cell lung cancer and small-cell lung cancer. The first type, which is the non small-cell lung cancer, is further divided into three types: adenocarcinoma, large cell carcinoma, and squamous cell carcinoma. The symptoms of non small-cell lung cancer include fatigue, persistent coughing, unexplained weight loss, chest pain, and bone aches, among others. There are a number of therapies and treatment methods that patients with non small-cell lung cancer can opt for. The non small-cell lung cancer treatment options depend on the stage of cancer. Occult cancer treatment This phase involves timely treatment during the early stages of cancer. In this phase, the malignant cells are not obvious in the bronchoscopy or imaging tests. These tests are repeated every few months to check if a tumor is present, and the rest of the treatment then depends on the stage of the tumor. Stage 0 non small-cell lung cancer The non small-cell lung cancer treatment options for this stage include laser therapy, photodynamic therapy, and brachytherapy. The next treatment option for this stage of cancer is surgery.

Cancer is the spread of abnormal cells in the human body that does not cease to reproduce. There are different categories of cancer, each deriving its name from the part where it originates. The treatment for the same will also depend on what part of the body is affected. Lung cancer may occur when a cancerous tumor starts growing near the lungs and affects its functioning. This cancer is further divided into two kinds of cancer: small cell lung cancer and non-small cell lung cancer. The latter spreads gradually and slowly than the former and it is more common in people. There are three kinds of non-small cell lung cancer, namely adenocarcinomas, squamous cell carcinomas, and large-cell carcinoma. Some of the early symptoms of non-small cell lung cancer are as follows. Persistent coughing While coughing at sometimes is all right, intense coughing that is persistent and does not seem to go away is one of the early signs of non-small cell lung cancer. If you have had a persistent cough that seems to only get worse or doesn’t improve with medicine, it is recommended to see a doctor to rule out the chances of it being something else. Abnormal weight loss This symptom is not limited to lung cancer but also applies to other categories of cancer as well.

Lymphocytic leukemia is a type of blood and bone marrow cancer. This disease grows rapidly and creates immature blood cells instead of mature ones. Lymphocytic leukemia is the most common type of cancer in children, and timely treatment can result in a good possibility for full recovery. It also occurs in adults but the chance of a cure is significantly lower. Signs and symptoms of lymphocytic leukemia The warning signs of this disease are as follows. Remember, symptoms vary from person to person. Bleeding in the gums Shortness of breath Pale skin Fever Lumps in or around the underarm, neck, groin, or abdomen Frequent infections Frequent or severe nosebleeds Weakness, extreme tiredness, or decrease in energy Symptoms due to low blood cell counts Most symptoms result from the decline in normal blood cells, which happens as a result of leukemia cells crowding red blood cells in the bone marrow. They result in symptoms such as tiredness, weakness, dizziness and lightheadedness, fever, shortness of breath, easy bruising, bleeding, and recurring infections. General symptoms Some patients show nonspecific symptoms, such as weight loss, night sweats, fever, fatigue, and a loss of appetite. These may also indicate other conditions, apart from lymphocytic leukemia.

Melanoma is a type of skin cancer that grows in a certain specific type of skin cell. Cancer outbreak begins when cancerous cells in our body spread and multiply. The top layer of the skin or epidermis is made up of squamous cells, basal cells, and melanocytes. These melanocytes help the skin from harsh ultraviolet (UV) radiation by producing melanin. But sometimes, these melanocytes behave in a weird pattern and grow in an uncontrolled manner by penetrating in the lower layers of skin, giving rise to cancer cells called melanoma. Melanoma produces a brown pigment called melanin and hence the color of our skin. Let us understand the causes and stats on melanoma, the worst type of skin cancer. The UV rays of the sun can damage the skin cells. Melanin safeguards the deeper layers of our skin from the sun rays. The reason behind darkening or tanning of the skin in sunlight is due to melanocytes producing more pigment. Causes of melanoma Most skin cancers are caused by constant exposure to the sun rays. It is said that UV-A and UV-B rays are the primary cause of melanoma. But melanoma cancer is caused by environmental location and partly due to genes.
