Why is Rare and Aggressive Cancer Difficult to Treat? Rare and aggressive cancers often present tough challenges that make them more difficult to treat than common tumor types. For a rare cancer case, doctors may not have a standard FDA-approved therapy to help guide them in clinical decision-making.

An atypical mole is not a skin cancer but having these moles is a risk factor for developing melanoma. Although rare, melanoma can arise in association with atypical moles. That is why it is important to be aware of these moles, get them checked by your dermatologist, and watch out for changing moles.

Primary lung sarcoma is a very rare malignant tumor, accounting for less than 0.5% of all lung tumors. The variety of soft tissue sarcomas reflects the range of the mesenchymal tissues present in the lung. The three most common sarcomas include leiomyosarcoma, malignant fibrous histiocytoma and synovial sarcoma.

Rare cancers are more difficult to diagnose than common cancers, and are thus more likely to be diagnosed at later stages, making them harder to treat. Lack of clinical expertise might lead to incorrect diagnoses, delaying access to the appropriate treatment.

How They Affect You. Atypical moles, also known as dysplastic nevi, are unusual-looking moles that have irregular features under the microscope. Though benign, they are worth more of your attention because individuals with atypical moles are at increased risk for melanoma, a dangerous skin cancer.

Duodenal ulcers are noncancerous (benign). Occasionally, gastric ulcers can be come cancerous (gastric cancer). Vomiting blood, passing black stools, or blood in the stool (blood loss) also may be signs of stomach cancer and peptic ulcers.

Gastric cancer, or stomach cancer, is cancer of the stomach. Gastric cancer occurs when cells in the lining of the stomach grow uncontrollably and form tumors that can invade normal tissues and spread to other parts of the body. Cancers are described by the types of cells from which they arise.

These lesions are predominately found in the duodenal bulb and small polyps are usually asymptomatic. They usually follow a benign course but dysplasia and malignancy have occasionally been reported.

Gastrointestinal stromal tumors (GISTs) may be malignant (cancer) or benign (not cancer). They are most common in the stomach and small intestine but may be found anywhere in or near the GI tract.

The earliest stage stomach cancers are called stage 0 (carcinoma in situ), and then range from stages I (1) through IV (4). As a rule, the lower the number, the less the cancer has spread. A higher number, such as stage IV, means cancer has spread more.

Zollinger-Ellison syndrome is a rare digestive disorder that results in too much gastric acid. This extra gastric acid can cause peptic ulcers in your stomach and intestine. Symptoms include abdominal pain, nausea, vomiting, weight loss, and diarrhea. If left untreated, there can be serious complications.

Bouvier des Flandres – Bouviers are predisposed to gastric carcinoma, a type of malignant stomach cancer. A cooperative study from Denmark and Norway looked for breed predisposition to gastric carcinoma, and they found that Bouviers fell into the high- risk group for developing this type of stomach cancer.

1) Brain cancers are rare. In the US, the incidence (that is, the number of newly diagnosed cases per year per 100,00 population) of all brain cancers is 6 cases per 100,000.
