An Early Sign of TSC
Heart Tumors Often Develop Before Birth
These tumors usually do not cause serious medical problems, but they are often the first recognized sign of TSC. The tumors are commonly found in the heart’s chambers, where they sometimes interfere with how your heart’s valves work. These tumors are often seen in people with TSC even before they are born. The good news is that the tumors often shrink and even disappear when children are very young.
