Dr. Pimple Popper lanced 2 lumps on a woman's back and 'bubble tea' cysts popped out

• Dr. Sandra Lee popped two cysts on a woman's back in her latest YouTube video.
• Cysts are sacks that form under the skin filled with bodily fluids.

In her latest video, Dr. Sandra Lee cut into a woman's back and popped out two cysts that she said looked like "boba" — the tapioca balls in bubble tea.

Better known as Dr. Pimple Popper, Lee documented the procedure on her official YouTube channel on Friday. In the video, Lee began by making an incision above the first cyst to expose it for extraction.

According to the Mayo Clinic, cysts are round bumps that form under the surface of the skin filled with bodily fluid. Lee explained why they are commonly found on our backs.

"They kind of burrow under here because our backs are so thick," Lee said in the video as she used her comedone extractor to dig out bits of the cyst.

Lee said it might be difficult to ensure the cyst doesn't grow back because it had broken apart in pieces under the skin. In order to fully extract a cyst and make sure it doesn't sprout again, the entire sac containing it needs to be removed. She said the broken cyst was likely caused by squeezing.

"When it's squeezed a lot it kind of pushes it in different directions so it's not all one nice shape," Lee said.

The second cyst Lee removed was smaller than the first and only an inch away. She used the tool to cut the bands connecting the cyst to her patient's skin before removing it. Lee squeezed it out easily by pushing the area around it with her fingers after loosening the cyst with her comedone extractor.

She said the cysts resembled boba because they were small and round like the popular tapioca balls.

"It's like a little baby boba that just popped," Lee said.

After Lee extracted all parts of both cysts, including the sac, she stitched up the incision and finished up with her patient's back.
