A few scientists do suggest that some triggers may be pathogens, such as viruses, fungi and bacteria, but there is no conclusive evidence that this is the case, notes Cleveland Clinic. In fact, what researchers know about sarcoidosis is that it is not linked to cancer nor is it a contagious condition. Similarly, sarcoidosis can develop in members of a family, but there is no current research that can conclusively show the exact link between this disease and genetics. However, certain ethnic groups, which include those of Irish, Scandinavian or German descent, may be at a greater risk for this disease, according to MedicineNet.

Some other facts associated with sarcoidosis are that it tends to affect people who are between the ages of 20 and 40, the disease can cause lung scarring and the condition is incurable.

Sarcoidosis is a condition in which there is inflammation in the tissues of different body organs, such as the lungs, eyes, skin, heart and lymph glands. The inflammation in the tissues causes nodules or masses called granulomas to develop in multiple body organs. Some symptoms of sarcoidosis are inflammation of joints that can cause pain, breathing difficulties, swollen lymph glands, blurry vision, arrhythmia and the development of bone cysts in areas that include the hands and feet, as stated by WebMD.
