Fibrous nodules are soft tissue cell growths that can develop almost anywhere in the body.
Solitary fibrous nodules are a rare disease with cancerous potential. These tumors must be resected if discovered incidentally during other surgical procedures or diagnosed preoperatively. The laparoscopic approach is considered advantageous for detecting and removing these tumors.
Is a fibrous tumor cancerous?
Most fibrous nodules are noncancerous (benign), but they can occasionally develop into cancerous (malignant) nodules. Fibrous nodules tend to grow slowly, and symptoms may not appear until the nodules get very large.
Fibrous nodules most frequently develop in the pleura, which lines the outside of the lungs. These nodules are called pleural solitary fibrous tumors. Additionally, fibrous nodules have been detected in the head and neck, breast, kidney, prostate, spinal cord, and other sites.
How are fibrous nodules diagnosed?
Imaging tests to assess fibrous nodules may include:
Your doctor may take a small tissue sample for microscopic inspection to confirm a suspected single fibrous tumor (biopsy). A diagnosis can be verified by an expert pathologist who can also determine whether the tumor is cancerous.
Should fibrous nodules be removed?
In most cases, surgery is the only treatment option for fibrous nodules. Surgeons remove the tumor along with a small margin of healthy tissue surrounding it. The operation performed to remove a solitary fibrous tumor is determined by where the tumor is located.
Your doctor may advise radiation therapy if the entire tumor cannot be removed. Before surgery, radiation therapy may be performed to reduce the tumor. Chemotherapy is an additional option for treatment, especially if the tumor has migrated to other parts of the body.
A number of medications specifically target tyrosine kinase signaling pathways and vascular endothelial growth factors. Recently, these pathways have started being used for the treatment of advanced solitary fibrous tumors as they halt the growth of tumors by interfering with their blood supply. These medications include:
- Votrient (pazopanib)
- Nexavar (bevacizumab)

CA 125 Ovarian Tumor Marker Blood TestCA 125 is a protein, and a tumor marker or biomarker. CA 125 is present in greater concentration in ovarian cancer cells than in other cells. CA stands for cancer antigen. Increases in CA 125 can also occur with malignant tumors of the Fallopian tubes, lining of the uterus, lung, breast, and gastrointestinal track. Benign conditions such as infections of the abdomen, chest, menstruation, endometriosis, benign tumors of the ovaries, and liver disease can also raise CA 125.
Can a CT Scan Tell if a Lung Nodule Is Cancerous?No, a computed tomography (CT) scan cannot tell with certainty whether a lung nodule is cancerous. It can only indicate an abnormal spot in the lung that is opaque. This opaque spot may or may not be cancer.

Is a Solitary Fibrous Tumor a Sarcoma?A solitary fibrous tumor (SFT) is an extremely rare type of sarcoma, accounting for 2% of all soft tissue sarcomas.

Cancer: Symptoms of Common Cancers in MenCan men get breast cancer? Cancer symptoms men need to watch out for include skin changes, difficulty swallowing, rapid weight loss, a breast mass, and more. Learn possible clues to finding and detecting cancer early.
Targeted Therapy: What Is Apoptosis in Cancer Cells?Cancer cells grow and proliferate endlessly. Targeted therapy to stimulate cell death or apoptosis can help keep tumors in check. Normal cells have a finite cell cycle of growth, division and differentiation. The final stage in the cell cycle is apoptosis, or programmed cell death, when they are infected, old, damaged or simply no longer needed.
Targeted Therapy: What Is the Function of A Tumor Suppressor Gene?Tumor suppressor genes encode proteins to modulate the process of cell growth and replication. Mutations which inactivate the tumor suppressor genes enable cancer cells to grow, unrestrained. Some targeted therapies aim to reactivate these genes, thus suppressing the tumor.
What Are the Most Common Soft Tissue Tumors?In adults, the most common types of soft tissue tumors include liposarcoma, undifferentiated pleomorphic sarcoma, and leiomyosarcoma.

What Exactly Is a Tumor?A tumor is an abnormal growth of cells, which serves no purpose in the body. There are three types of tumors, but it is not always clear how a tumor will develop in the future. Some non-cancerous tumors can become cancerous. Early detection of a lump or tumor is important to determine what will be the treatment.
What Is a Grade 4 Tumor?In grade 4 cancer, tumor cells look very different from the normal cells, and most likely, they have spread to distant organs. Such tumors have a poorer outlook and may need more aggressive management. Usually, tumors in grade 4 are undifferentiated and very aggressive.
