What type of tumor is known to be non-cancerous that affects the intestines?

Benign lipomas are non-cancerous tumors that can occur in various body tissues, including the intestines. They are composed primarily of adipose (fat) tissue and are characterized by their slow growth and lack of invasive properties. Lipomas are usually asymptomatic and do not typically cause health issues unless they are located in a position that exerts pressure on surrounding organs or tissues.

In contrast, malignant gastroenteromas, adenocarcinomas, and squamous cell carcinomas are all types of cancerous tumors. Malignant gastroenteromas are neuroendocrine tumors that can secrete hormones and are aggressive. Adenocarcinomas are cancers of glandular tissue and can arise in various areas, including the intestines, leading to significant health complications. Squamous cell carcinoma typically originates from squamous cells and is associated with malignancy and invasive growth.

Therefore, identifying lipomas as benign emphasizes their non-cancerous nature and distinguishes them from the more severe implications of the other options.
