The 7 most common cancers are:

1. Lung cancer
2. Breast cancer
3. Prostate cancer
4. Colorectal cancer
5. Skin cancer (Melanoma)
6. Bladder cancer
7. Non-Hodgkin lymphoma

Lung cancer

Lung cancer is a type of cancer that starts in the lungs. The lungs are two spongy organs in the chest that take in oxygen and release carbon dioxide. There are two main types of lung cancer: non-small cell lung cancer and small cell lung cancer. Non-small cell lung cancer is more common and tends to grow and spread more slowly than small cell lung cancer. Symptoms of lung cancer may include a cough that doesn't go away, chest pain, shortness of breath, and weight loss. Risk factors for lung cancer include smoking, exposure to secondhand smoke and other pollutants, and a family history of lung cancer.

If you are concern about lung cancer please contact your doctor for proper diagnosis and treatment.

Breast cancer

Breast cancer is a type of cancer that starts in the cells of the breast. It is the most common cancer in women worldwide and the second most common cancer overall. It can occur in both men and women, but it is rare in men. There are different types of breast cancer, but the most common type is ductal carcinoma, which starts in the cells of the ducts (the tubes that carry milk from the lobules to the nipple). Another common type of breast cancer is lobular carcinoma, which starts in the lobules (the glands that make milk).

Symptoms of breast cancer may include a lump or thickening in the breast or underarm, changes in the size or shape of the breast, and changes in the skin of the breast, such as dimpling or redness. Risk factors for breast cancer include being a woman, getting older, having a family history of breast cancer, having certain gene mutations, and certain lifestyle factors such as alcohol consumption and obesity.

If you are concern about breast cancer please contact your doctor for proper diagnosis and treatment.

Prostate cancer

Prostate cancer is a type of cancer that starts in the prostate, a small gland in the male reproductive system located just below the bladder and in front of the rectum. It is the most common cancer in men and the second most common cause of cancer death in men worldwide. The prostate gland produces semen, the fluid that carries sperm.

Symptoms of prostate cancer can be similar to symptoms of an enlarged prostate and may include difficulty starting or stopping urination, weak or interrupted urine flow, and frequent urination, especially at night. However, many men with prostate cancer do not have any symptoms and the cancer is found during a routine screening test or for other reasons.

Risk factors for prostate cancer include age, family history, and being of African-American descent.

If you are concern about prostate cancer please contact your doctor for proper diagnosis and treatment. Early detection and treatment can improve the chances of successful outcome.

Colorectal cancer

Colorectal cancer, also known as colon cancer or rectal cancer, is a type of cancer that starts in the colon or rectum. The colon and rectum are parts of the large intestine, and their main function is to remove water and salt from solid waste and store the waste before it is eliminated from the body.

Colorectal cancer usually develops from precancerous polyps (abnormal growths) in the colon or rectum. These polyps can be benign, but some can become cancerous over time. Symptoms of colorectal cancer may include a change in bowel habits, such as diarrhea or constipation, or a change in the consistency of the stool, rectal bleeding, abdominal pain or cramps, and weakness or fatigue.

Risk factors for colorectal cancer include age, family history of colorectal cancer or polyps, personal history of inflammatory bowel disease, such as ulcerative colitis or Crohn's disease, lifestyle factors such as diet low in fruits and vegetables and high in red or processed meat and alcohol consumption, and obesity.

Screening tests such as colonoscopy, fecal occult blood test, and stool DNA test are available to detect colorectal cancer at an early stage, when it is most treatable.

If you are concern about colorectal cancer please contact your doctor for proper diagnosis and treatment.

Skin cancer

Skin cancer is a type of cancer that starts in the cells of the skin. There are three main types of skin cancer: basal cell carcinoma, squamous cell carcinoma, and melanoma.

Basal cell carcinoma is the most common type of skin cancer and it develops in the basal cells, the cells that line the deepest layer of the epidermis (the outermost layer of the skin). They tend to grow slowly and usually don't spread to other parts of the body.

Squamous cell carcinoma is the second most common type of skin cancer and it develops in the squamous cells, the cells that make up the middle layer of the epidermis. They can spread to other parts of the body if left untreated.

Melanoma is a less common but more aggressive type of skin cancer that develops in the cells that produce pigment (color) in the skin. Melanoma can spread to other parts of the body if not caught and treated early.

Symptoms of skin cancer may include a new spot or growth on the skin, a change in the size, shape, color, or texture of an existing spot or growth, or a sore that does not heal. Risk factors for skin cancer include exposure to ultraviolet (UV) radiation from the sun or tanning beds, fair skin, family history of skin cancer, and having many moles or atypical moles.

It is important to be aware of your skin, and if you notice any changes in your skin, please contact a doctor or a dermatologist for proper diagnosis and treatment.

Regular skin self-examination and regular skin check-ups can help detect skin cancer early when it is most treatable.

Bladder cancer

Bladder cancer is a type of cancer that starts in the urinary bladder. The urinary bladder is a muscular sac in the pelvis that stores urine before it is eliminated from the body. Bladder cancer is a relatively common type of cancer, especially in older adults.

There are several types of bladder cancer, the most common being transitional cell carcinoma (TCC), which starts in the cells that line the inside of the bladder. Other types include squamous cell carcinoma and adenocarcinoma.

Symptoms of bladder cancer may include blood in the urine (hematuria), frequent urination, painful urination, and lower back pain. Risk factors for bladder cancer include smoking, exposure to certain chemicals, a family history of bladder cancer, and having certain medical conditions such as chronic bladder infections.

If you are concern about bladder cancer please contact your doctor for proper diagnosis and treatment. Diagnosis can be done through urine test, cystoscopy, and biopsy. Treatment options include surgery, radiation therapy, and chemotherapy.

Bladder cancer has a high rate of recurrence, so regular check-ups and follow-up care are important to detect any recurrence early.

Non-Hodgkin lymphoma

Non-Hodgkin lymphoma (NHL) is a type of cancer that starts in the lymphocytes, a type of white blood cell that helps the body fight infections. The lymphocytes can start to grow and multiply uncontrollably, forming a mass called a lymphoma. Non-Hodgkin lymphoma is a broad term that includes many different types of lymphomas, which can differ in how quickly they grow and spread, and how they respond to treatment.

Symptoms of Non-Hodgkin lymphoma can include swollen lymph nodes, fever, weight loss, fatigue, night sweats, and shortness of breath. The symptoms can be similar to those of other illnesses, so a proper diagnosis can only be made with a biopsy.

The exact cause of Non-Hodgkin lymphoma is not known, but certain factors are associated with an increased risk of developing the disease, such as having a weakened immune system, exposure to certain chemicals and pesticides, and having a family history of Non-Hodgkin lymphoma.

Treatment options for Non-Hodgkin lymphoma can vary depending on the type and stage of the disease and can include chemotherapy, radiation therapy, immunotherapy, targeted therapy, and stem cell transplant.

If you are concern about Non-Hodgkin lymphoma please contact your doctor for proper diagnosis and treatment. Early detection and treatment can improve the chances of a successful outcome.
