There are different types of cancer such as Carcinoma, sarcoma leukemia, etc. Cancer is a disease that affects the growth & division of cells. It can occur in many different forms & can come from almost any type of organ. Cancer is a complex disease that is caused by a variety of factors including genetics, environment & lifestyle. These factors can cause mutations in genes that regulate cell division, leading to uncontrolled cell growth & the growth of tumors. In this article, we will learn about cancer types, and how cancer is different from normal cells.

Definition of Cancer
Cancer is a disease characterized by abnormal cell division, often forming tumors that can invade nearby tissues and affect normal bodily functions.
What is Cancer?
Cancer is a multifactorial disease that is characterized by uncontrolled cell proliferation & the proliferation of abnormal cells that can enter surrounding tissues. It starts with a genetic mutation that causes normal cells to change into cancer cells resulting in the growth of tumors. These abnormal cells can then multiply out of control, causing damage to organs and tissues. It can affect almost any area of the body & can be cancerous. Benign tumors are non-cancerous & do not spread to other organs. On the other hand, malignant tumors and cancers can invade surrounding tissues and spread to distant locations via the bloodstream & the lymphatic system.

Types of Cancers
- Breast cancer: Breast cancer is one of the most common cancers of the breast. It is a cancer of the breast tissue. It is usually found in the milk duct in the lobules of the breast. Breast cancer can be invasive. Ductal carcinoma of the in situ breast is the most common type of breast cancer.
- Lung cancer: Lung cancer is the most common cancer that starts in the lungs. It is caused by the abnormal growth of cells in the lung tissues. Lung cancer is mainly caused by tobacco use.
- Colorectal cancer: Cancer of the large intestine including colon & rectal cancer is a major global health issue. The disease is usually caused by cancerous growths known as polyps which are abnormal masses of tissue that can become cancerous over time.
- Prostate cancer: Prostate cancer is an aggressive cancer that starts in the prostate. Prostate cancer occurs when abnormal changes occur in prostate cells & they begin to multiply out of control.
- Pancreatic cancer: Pancreatic cancer is one of the most common causes of cancer in the human body. Common risk factors include smoking a family history of pancreatic cancer chronic pancreatitis certain genetic diseases. Because there are no specific symptoms early detection is still a major challenge.
- Brain tumors: Brain tumors are tumors of abnormal cells in the brain. They can be benign or malignant in nature. Benign tumors are not cancerous & usually grow slowly.
- Liver cancer: Hematocellular carcinoma is a type of cancer that primarily affects the liver cells. HCC is often associated with chronic liver disease especially cirrhosis which is caused by chronic hepatitis B, excessive consumption of alcohol, non alcoholic fatty liver disease & certain genetic diseases.
- Ovarian cancer: Ovarian cancer develops in the ovaries, the female reproductive organs. Often evading early detection, it tends to spread within the pelvis and abdomen. Symptoms may manifest as bloating, pelvic pain, and difficulty with eating.
- Bladder cancer: Bladder cancer originates in the bladder lining, responsible for urine storage. Recognizable symptoms encompass blood in the urine, pain during urination, and frequent urinary tract infections.
- Kidney cancer: Kidney cancer initiates in the kidneys, essential for filtering waste from the blood to produce urine. Indicators often include blood in the urine, persistent back pain, and the presence of a mass or lump in the abdominal region.
- Thyroid cancer: Thyroid cancer arises in the thyroid gland, located in the neck. Detection is frequently linked to the identification of a lump in the thyroid or through imaging tests. Symptoms may include difficulty swallowing, hoarseness & swollen lymph nodes.
- Esophageal cancer: Esophageal cancer affects the esophagus, the conduit for transporting food from the throat to the stomach. Risk factors involve smoking and excessive alcohol consumption. Symptoms encompass difficulty swallowing, weight loss & chest pain.
Main Types of Cancer
Carcinoma
Carcinoma is a type of cancer that develops from the epithelial cells that make up the lining of the body tissues & organs. Cervical cancer is the most widespread type of cancer with subtypes such as lung cancer, adenocarcinoma & squamous cell carcinoma.
Sarcoma
Sarcoma is a type of cancer that occurs in connective tissues. These connective tissues include bones, muscles & blood vessel. Sarcoma is a very rare type of cancer but it can be very aggressive. Diagnosis & treatment of sarcomas requires a multi disciplinary approach including surgery, radiation & chemotherapy.
Leukemia
Leukaemias are blood cancers & bone marrow cancers that cause abnormal production of white blood cells. There are acute and chronic forms. Symptoms of cancer can range from tiredness to increased risk of infections. Chemotherapy, targeted therapies & stem cell transplants are all part of the treatment.
Leukemia a form of blood cancer, affects the bone marrow and blood. It disrupts the normal production of white blood cells, leading to fatigue, susceptibility to infections & easy bruising.
Lymphoma & Myeloma
Lymphomas are a type of cancer that affects the lymphatic system. There are two types of lymphomas as Hodgkin & Non hodgkin lymphomas. Lymphoma is a malignancy originating in the lymphatic system, a vital component of the immune system. Symptoms of cancer often include swollen lymph nodes, fever, and unexplained weight loss.
Myeloma is a cancer that affects the plasma cells that make up the bone marrow. They both involve abnormal cell growth with therapies such as chemotherapy, immunotherapy & stem cell transplantation. Melanoma, a type of skin cancer, emerges from the pigment-producing cells responsible for skin color. Recognizing changes in mole size, shape, or color is crucial for early detection, as melanoma can swiftly metastasize to other body parts.
Brain and Spinal Cord Cancers
Brain and spinal cord cancers encompass diverse tumors arising within the central nervous system. Examples include glioma, meningiomas & medulloblastomas.
Causes of Cancer
Tha main cause which leads to cancer are given below:
- Genetic factors: Cancer is a complex group of diseases influenced by a combination of genetic, environmental and lifestyle factors. Genetic mutations are either inherited and acquired throughout a person life and play an important role.
- Environmental factors: One of the most important environmental factors is exposure to carcinogens. Carcinogens are substances that increase the risk of developing cancer. Tobacco smoke, uv radiation, chemicals & viruses such as HPV, hepatitis B & C.
- Lifestyle factors: Cancer risk is determined by lifestyle factors including poor diet, sedentary lifestyles & obesity. Consumption of high processed foods, low fruits/vegetables & high in red processed meats are linked to a higher risk of cancer. Another risk factor for cancer is chronic inflammation which is often caused by conditions such as inflammatory bowel disease.
- Hormonal changes: Another risk factor is exposure to high levels of ionizing radiation. Hormonal changes such as hormone replacement therapy & prolonged use of oral contraceptives can affect the development of cancer in specific tissues.
- This knowledge and problem solving is essential for cancer prevention approaches which often include lifestyle changes, infection prevention, early detection through screening & reducing exposure to well known carcinogens.
