Cancer

Cancer Cancer is a physical condition of abnormal cell division . Cancer is alarmingly increasing and death rate due to cancer is also increasing in alarming rate. There have a specific types of causes of happenning cancer. The exact identified cause of cancer is so called genetic mutation. Researcher in  Stanford University identified the specific cause of cancer as the result of genetic mutation. Simply to say that genetic mutation is cause of cancer Severe types of cancer Among a lot of cancer there have specific types of cancer that significantly causes death. A list of these cancer disease is given bellow, Breast cancer Cervical cancer Lung cancer Breast cancer Breast cancer  is one of the most common cause of women death worldwide. A huge range of women worldwide died per year due to breast cancer. The abnormal cell division in breast cell when occur in uncontrobale rate the condition is called breast cancer. When it is untreated that spread to othe

Bone cancer

Bone cancer Bone cancer is a types of cancer that starts at bone then it may spread by metastasis.  The abnormal cell division of bone cell is responsible to cause bone cancer.  Symptom of Bone cancer Symptom is bone cancer is sometime shown in rest time. During rest there found the specific types of site of bone shows pain. The pain may be very severe in night time at sleep.

Cervical cancer

Cervical cancer Cervical cancer is one of the most common cause of women death worldwide. It is a infectious disease. It is termed as STD type disease. The responsible virus of cervical cancer is HPV. HPV means Human Pappilloma Virus. After infecting by HPV virus the cell of cervix struggled to survive. A special types of genetic mutation caused. Started abnormal cell division. As a result causes cancer. Very alarming is that in most case the symptom of cervical cancer is not diagnosed and from a several year it remain hide. Sometimes a few symptom may found concerned with cervical cancer. These are vaginal bleeding, pelvic pain and pain during sexual intercourse. The major types of cervical cancer is squamous cell carcinoma and adenocarcinoma.

Lung Cancer

Lung Cancer Lung cancer is a condition of abnormal cell division of Lung cell. Lung is a respiratory system main organ placed inside the chest cavity. Main function of lung is insertion of Oxygen and excretion of Carbon-Di-Oxide from the body. When abnormal cell division happens in lung cell due to abnormal DNA sequence then a footstep of carcinoma caused. Besides of other types of cancer such as Breast cancer, Cervical cancer, Bone cancer Lung cancer is also a life threatening cancer that causes significantly death if it left untreated. There are two main types of Lung cancer Non-small cell Lung cancer Small cell lung cancer Another special types of lung cancer is lung Carcinoid tumor. Most of the lung cancer is non-small cell lung cancer. About 85% of lung cancer is non-small cell lung cancer. Squamous cell lung cancer, Adenocarcenoma and large cell carcinoma is such types of non-small cell lung cancer.

Genetic mutation is a cause of cancer

Genetic mutation Genetic mutation is a common cause of cancer. At first Stanford University researcher found that the unique important cause of cancer is genetic mutation.  Genetic mutation is a permanant alteration of DNA sequence. In simply to say that genetic mutation is changes in the DNA sequence. But we know that mutation is a normal process in animals and plants. For the cause of genetic mutation the diversity of animals and plants causes. Not each of the molecular changes we can say as mutation. Such types of molecular change that affect the nucleic acid we may refer as genetic mutation. Nucleic acid is the main component of DNA. But in terms of Virus nucleic acid is the building block of both RNA and DNA. In terms of evolutionary concept to survibal need somatic mutation happens.Somatic is the body related. Soma means body and it is a greek word. As same cancer caused due to somatic mutation. cell mutation due to the survival need.

Abnormal cell division

Cell division Cell division is a normal process of living organism for their growing up and reproduction.  There have two major type of cell division. Mitosis cell division Meiosis cell division Abnormal cell division In 1890 a German researcher,  David Hanseman found an abnormal cell division when these dividing through mitosis cell division. But he could not found that why it is happening such types of cell division. David Gisselsson fron Lund University gives an idea why should abnormal cell division happens.  David Gisselsson have a wide range of study on chromosome number change in cancer cell.  An example may give that the chromosome number in cancer cell is deviated from the chromosome number in normal cell. Normal cell chromosome number is 46. But in skeletal and pancreatic cancer some cell may found that the chromosome number different from 46. Scientists of Lund University during mitosis cell division a certain types of cell faces with abnormaliti
