Kris Jenner gets emotional during The Kardashians season five trailer when she told her family that she has a tumor. The trailer was released Wednesday (May 8) and it took her daughters and fans by a huge surprise when she made the announcement.

“I had my scan,” an emotional Kris Jenner explains, with boyfriend Corey Gamble sitting down next to her.  “They found a cyst and like a little tumor.”

Kris doesn't go much more into details in the trailer but Khloe, Kendall and Kylie are shown in the clip getting emotional over the news.

Elsewhere in the trailer, another medical scare takes over the family from Kourtney Kardashian. This season we will get an inside look of how Kourtney handled the emergency fetal surgery behind the scenes. If you recall, back in September, Kourtney was rushed to the hospital when she was pregnant with her son Rocky Thirteen whom she shares with Travis Barker. Shortly after her visit, she took to social media to tell fans about the surgery.

“I will be forever grateful to my incredible doctors for saving our baby’s life,” Kourtney began her caption on the photo.

“I am eternally grateful to my husband who rushed to my side from tour to be with me in the hospital and take care of me afterwards, my rock. And to my mom, thank you for holding my hand through this,” she continued.

“As someone who has had three really easy pregnancies in the past, I wasn’t prepared for the fear of rushing into urgent fetal surgery. I don’t think anyone who hasn’t been through a similar situation can begin to understand that feeling of fear,” she added. “I have a whole new understanding and respect for the mamas who have had to fight for their babies while pregnant.”

She concluded, “Praise be to God. Walking out of the hospital with my baby boy in my tummy and safe was the truest blessing.”

Besides the emotional moments with the health scares, you see the family having fun on vacation and Kendall joking about Kylie making her wait.

“Kylie just made me wait an hour for her to do a photoshoot,” Kendall says.

“Whatever!” Kylie jokes before excitedly screaming, “It's fashion week!”

There's also some drama between Khloe and Kim. The SKIMS founder is seen talking to Kris about an topic revealed off screen and the matriarch suggests that she asks Khloe for advice.

“No, she's just very judgmental now that Tristan [Thompson] is gone,” Kim says back.

Kim also says in another scene, “Khloe is unbearable these days.”

“Sisters can be vicious and brutal,” Khloe is heard saying in a confessional and later confronts Kim later,”You are going through a lot right now and you're taking it out on me.”

Season five of The Kardashians premieres May 23 on Hulu. Take a look at the full trailer below:
