Lung Cancer – A disease characterized by uncontrolled cell growth in the tissues of the lung. It often begins in the cells lining the bronchi and parts of the lung such as the bronchioles or alveoli. As it progresses, it can spread to other parts of the body, including the lymph nodes and brain. Symptoms may include persistent cough, chest pain, and shortness of breath. The disease can be classified into small cell lung cancer and non-small cell lung cancer, each with different growth patterns.
Renal Cell Carcinoma – A type of kidney cancer that originates in the lining of the proximal convoluted tubule. It is the most common type of kidney cancer in adults. The disease may initially present with symptoms such as blood in the urine, flank pain, and a mass in the abdomen. As it progresses, it can spread to nearby tissues and distant organs. The cancer cells can grow into a large mass and may invade the renal vein or spread to the lungs and bones.
Head and Neck Cancer – A group of cancers that originate in the squamous cells lining the moist surfaces inside the head and neck. These cancers can affect areas such as the mouth, throat, and larynx. Symptoms may include a lump or sore that does not heal, a persistent sore throat, and difficulty swallowing. As the disease progresses, it can spread to lymph nodes and other parts of the body. Risk factors include tobacco use, alcohol consumption, and human papillomavirus (HPV) infection.
Urothelial Carcinoma – A cancer that occurs in the urothelial cells lining the bladder, ureters, and other parts of the urinary tract. It is the most common type of bladder cancer. Symptoms may include blood in the urine, frequent urination, and pain during urination. As it progresses, it can invade the bladder wall and spread to nearby lymph nodes and organs. The disease is often linked to smoking and exposure to certain industrial chemicals.
Triple Negative Breast Cancer – A subtype of breast cancer that lacks estrogen, progesterone, and HER2 receptors. It tends to be more aggressive and has fewer treatment options compared to other breast cancer types. Symptoms may include a lump in the breast, changes in breast shape, and skin dimpling. The cancer can spread to other parts of the body, including the lymph nodes and lungs. It is more common in younger women and those with a BRCA1 gene mutation.
Merkel Cell Carcinoma – A rare and aggressive skin cancer that originates in the Merkel cells located in the skin. It often appears as a painless, fast-growing nodule on sun-exposed areas of the skin. The disease can quickly spread to nearby lymph nodes and distant organs. Risk factors include excessive sun exposure, a weakened immune system, and infection with the Merkel cell polyomavirus. Early detection is crucial due to its rapid progression.
Melanoma – A type of skin cancer that develops from the pigment-producing melanocytes. It is known for its ability to spread to other parts of the body if not detected early. Symptoms include changes in the size, shape, or color of a mole or the appearance of a new mole. The disease can invade nearby tissues and metastasize to organs such as the lungs and brain. Risk factors include excessive sun exposure and genetic predisposition.
Hepatocellular Carcinoma – The most common type of primary liver cancer, originating in the hepatocytes. It often develops in the context of chronic liver disease, such as cirrhosis or hepatitis infection. Symptoms may include abdominal pain, weight loss, and jaundice. As it progresses, the cancer can invade blood vessels and spread to other parts of the body. Early stages may not present noticeable symptoms, making regular monitoring important for at-risk individuals.
Colorectal Carcinoma with Microsatellite Instability – A form of colorectal cancer characterized by genetic hypermutability due to defects in the DNA mismatch repair system. It often presents with symptoms such as changes in bowel habits, blood in the stool, and abdominal discomfort. The disease can spread to nearby lymph nodes and distant organs like the liver and lungs. Microsatellite instability is associated with a better response to certain immunotherapies. It is often linked to hereditary conditions like Lynch syndrome.
Esophageal Squamous Cell Carcinoma – A type of esophageal cancer that begins in the flat, thin cells lining the esophagus. It is more common in the upper and middle parts of the esophagus. Symptoms may include difficulty swallowing, chest pain, and weight loss. As it progresses, the cancer can invade deeper layers of the esophagus and spread to nearby lymph nodes and organs. Risk factors include smoking, heavy alcohol consumption, and dietary habits.
Endometrial Carcinoma – A cancer that originates in the lining of the uterus, known as the endometrium. It is the most common type of uterine cancer. Symptoms often include abnormal vaginal bleeding, pelvic pain, and weight loss. The disease can spread to the myometrium, cervix, and distant organs if not detected early. Risk factors include obesity, hormone replacement therapy, and a history of polycystic ovary syndrome.
Cervical Cancer – A cancer that occurs in the cells of the cervix, the lower part of the uterus that connects to the vagina. It is often caused by persistent infection with high-risk types of human papillomavirus (HPV). Symptoms may include abnormal vaginal bleeding, pelvic pain, and pain during intercourse. As it progresses, the cancer can invade nearby tissues and spread to distant organs. Regular screening and HPV vaccination can help prevent the disease.
Gastric/Gastro-Esophageal Junction/Esophageal Adenocarcinoma – A type of cancer that forms in the glandular cells of the stomach or the junction where the stomach meets the esophagus. Symptoms may include difficulty swallowing, weight loss, and abdominal pain. The disease can spread to nearby lymph nodes and distant organs such as the liver and lungs. Risk factors include chronic gastroesophageal reflux disease (GERD), obesity, and smoking. Early detection is challenging due to nonspecific symptoms.
Basal Cell Carcinoma – The most common type of skin cancer, originating in the basal cells of the epidermis. It often appears as a small, shiny bump or a pink growth on sun-exposed areas of the skin. The cancer grows slowly and rarely spreads to other parts of the body. However, it can cause significant local damage if left untreated. Risk factors include prolonged sun exposure and fair skin.
Squamous Cell Carcinoma of the Skin – A common form of skin cancer that begins in the squamous cells of the epidermis. It typically appears as a red, scaly patch or a sore that may crust or bleed. The cancer can grow into deeper layers of the skin and spread to other parts of the body. Risk factors include excessive sun exposure, a history of sunburns, and a weakened immune system. Early detection and treatment are important to prevent complications.
