Tumor diseases of the brain
Brain tumors are classified according to their cells of origin. They can be either benign or malignant. The WHO classification is used for this classification. The symptoms of a brain tumor are varied and usually allow conclusions to be drawn about the location of the tumor. Information on the individual forms of brain tumors can be found here: Astrocytoma Glioblastoma Medulloblastoma Meningeoma Oligodendroglioma Angioblastoma Pituitary tumor Acoustic neuroma Information on the individual forms of brain tumor can be found under
- Astrocytoma
- Glioblastoma
- Medulloblastoma
- Meningioma
- Oligodendroglioma
- Angioblastoma
- Pituitary tumor
- Acoustic neuroma
Tumor diseases of the eye
That the eyelid consists of skin, all forms of skin cancer can occur, such as a basal cell carcinoma or a melanoma. Since this area is strongly exposed to the sun, especially basaliomas often occur on the eyelid. These can usually be surgically removed and healed.
Tumors at the lacrimal gland are more often benign than malignant. The most frequent benign tumor of the lacrimal gland is the adenoma. Malignant tumors are very rare.
This is often a mixed tumor. Uveal melanoma is the most common malignant tumor inside the eye and is caused by a degeneration of the pigment-forming cells. Depending on size, cell type and whether metastasis is present, the prognosis is very different.
Tumor diseases of the internal organs
Colorectal cancer is a malignant, degenerative, uncontrollably growing tumor that originates from the cells of the colon mucosa. In most cases, colorectal cancer develops in the area of the colon.Information on the different forms of colorectal cancer can be found at Small colorectal cancer Colorectal cancer Rectal cancer Anal carcinoma Information on the individual forms of colorectal cancer can be found at

Stomach cancer (carcinoma of the stomach) is the fifth most common cancer in women and the fourth most common cancer in men. Stomach carcinoma is a malignant, degenerated, uncontrollably growing tumor that originates from the cells of the stomach lining.
The causes of stomach cancer are discussed to include nitrosamines from food, nicotine and Helicobacter pylori. In most cases, the tumor causes symptoms late in the disease, when it is already well advanced. Due to the late diagnosis, stomach cancer is often treated late, so that this type of cancer has a rather unfavorable prognosis for the patients.
Pancreatic cancer = pancreatic carcinoma (ductal adenocarcinoma of the pancreas) is by far the most common cancer of the pancreas. It belongs to the malignant neoplasms. Benign tumors (including, for example, serous cystadenocarcinoma) or other malignant forms (mucinous cystadenocarcinoma, acinar cell carcinoma) are very rare.
In most cases, pancreatic cancer occurs in the front part of the pancreas, the so-called head of the pancreas. You can find information on the individual forms of pancreatic cancer at Insulinoma Verner-Morrison-Snydrome Information on the individual forms of pancreatic cancer can be found at

Peritoneal cancer rarely develops from peritoneal cells. Much more frequently, metastases from tumors from surrounding organs settle in the peritoneum.
Often affected patients have water in their abdomen, which can be detected with the help of ultrasound. The prognosis often depends on the original tumor and further metastases. Gall bladder cancer is a malignant tumor, but it occurs quite rarely.
However, since it is often diagnosed late, it has a rather poor prognosis. Patients may have painless jaundice as a symptom, but this does not occur until a late stage. Bile duct cancer is a rare tumor and occurs significantly less frequently than gallbladder cancer.
It is a tumor of the bile duct mucosa that grows very slowly and only forms metastases at a late stage. Since it is often diagnosed late, it still has a relatively poor prognosis. Autoimmune diseases such as ulcerative colitis or primary sclerosing cholangitis are risk factors for the development of bile duct carcinoma.
Liver cancer often develops at the base of liver cirrhosis. But metastases from other tumors can also settle in the liver. Many of those affected suffer from hepatitis or have excessive alcohol consumption, but other people can also develop liver cancer.
Lung cancer is a malignant tumor. It develops from the tissue of the bronchi, but can consist of different types of cells. The most common are squamous and small cell bronchial carcinomas.
Symptoms can be chronic cough, recurring pneumonia or shortness of breath. Smoking, environmental toxins or genetic factors are risk factors for the development of lung cancer. A pheochromocytoma is a tumor of the adrenal gland.
It often produces the hormones arenalin and noradrenalin, but can also produce dopamine. Then it is a malignant tumor. The affected patients often have high blood pressure, palpitations, suffer from increased sweating and are pale.
Multiple endocrine neoplasia is an autosomal-dominant inherited disease, but can also occur sporadically. Depending on which organ is affected, different hormones are produced. Therefore the clinical picture is very variable.
