There are over 200 types of cancer, and each of these affects a different organ/part of the body. These cancers present several symptoms at different stages of the disease. Breast cancer and melanoma are the most common kinds with more than 40,000 cases in a year. Lung and prostate cancer are the other forms of the disease that are also very common. Here are a few details about the most common types of cancer.

• Breast Cancer: Breast cancer is a rare occurrence in men, but it is one of the most common types of cancer in women. In addition to fat, the breast is made up of lobules that contain milk ducts. The healthy cells in the breast may change and grow out of control as the disease develops. There are benign and malignant breast cancers. The malignant cancers can grow and spread to other parts of the body. However, the benign ones grow without spreading to other parts of the body.
• Melanoma: Your skin is the largest organ in the body, and melanoma is one of the most dangerous types of skin cancer, although not the most common. Melanocytes that are in the epidermis are responsible for the color of the skin. Melanoma is triggered when these healthy melanocytes begin to grow out of control. The triggers and start of melanoma may differ among people. For some, it may begin as patchy and scaly skin that refuses to heal, and for others, it may be a mole that seems to be changing shape and size. Early diagnosis is critical when it comes to treating melanoma.
• Lung Cancer: Smoking is the number one cause for developing lung cancer, but even non-smokers can develop the disease. It is one of the most common types of cancer, and it is treatable irrespective of the size, location, spread, or stage of cancer. There are epithelial cells in the lungs that line the airways. These cells manufacture mucus that works to lubricate and protect the lungs. When healthy cells regenerate uncontrollably, it can become a tumor. There are two main types of lung cancer: small cell lung cancer and non-small cell lung cancer.
• Prostate Cancer: Prostate cancer develops in the gland that produces seminal fluid. The walnut-sized prostate gland produces semen and transfers the same too. Several symptoms have been reported in this type of cancer. The main symptoms are difficulty in urination, and blood in the seminal fluid, among others. Many times, the symptoms do not show up for several years. This cancer progresses quite slowly too. However, there are a few kinds of prostate cancer that require aggressive forms of treatment.

These are the most common types of cancer that you will come across. Understanding the symptoms and your risks will help you to stay in control of your health.
