This Sister's Cancer Dance Brings a Smile to the Internet

One of the best friends you will ever have in this world will be your sister. You will know more about one another than anyone else. You will know what she looks like before she has her coffee in the morning. You will know if she is in a bad mood without asking. Most of all, you will know exactly how to cheer her up.

The woman in this video, which has gone viral, is clearly a very good sister.

Trying to bring a smile to her sister's face during her seventh round of chemotherapy, this unknown woman filmed herself dancing to Cali Swag District's "Teach Me How to Dougie." She holds nothing back in her attempt to make her sister smile.

The video has struck a chord. It has been shared over 50,000 times on Facebook and viewed more than 2.7 million times so far. There are thousands of encouraging comments.

Here's the full video:

Toward the end of the video, when the dancing stops, the woman sends out a message of support to her sister, and all sisters, saying, "You're going to kick cancer's ass today because you're a badass sister. … I love you with all my heart and my soul. That's about it for today! I admire you. Later, gator!"
