Fans can't help but worry about BLACKPINK's Jisoo's health after seeing a lump on her neck. This results in different assumptions about her well-being, with some saying it may be a cause of an illness while others think it's just normal.

BLACKPINK is now busy with their world tour, "Born Pink." So, they even get more worried about Jisoo and the rest of the girls' health.

In a post on an online community, via AllKpop, a netizen shared several photos of Jisoo to show the lump on her neck. One fan asked if it wasn't a tumor, while others advised her to go to the hospital and have it checked or undergo a biopsy.

"It could be a mild fibroid, but it could also be a malignant tumor," another claimed. The fan noticed that it kept getting bigger and might only disappear if she opted for surgery.

However, others said it wasn't a big deal, and there was nothing to worry about. The netizen explained that things like it started to form when someone was tired, so it would probably just disappear if Jisoo rested. In fact, this fan explained that when he had his checked, the doctors said it was okay, and it just swelled.

The lump is said to be a lymph node, and it swells when a person isn't in good condition or tired. As one of the most famous K-pop stars today, Jisoo is surely getting her health checked.

Meanwhile, despite being busy with BLACKPINK's "Born Pink" world tour, Jisoo still found time to support her friend, Girl's Day's Hyeri, by sending her a gift on the set of her new drama, "May I Help You?"

In a post on Instagram on October 29, the singer-actress revealed that Jisoo sent her a coffee-and-churros truck. Hyeri was evidently delighted, as seen in her photos, posing happily in front of the truck and holding a candy bag and huge churros. The last snap saw her with Jisoo herself.

In the caption, Hyeri wrote that Jisoo might be busy with BLACKPINK's hectic world tour, but she still sent her a coffee, churros, and snacks truck. That said, she was even more grateful, calling Jisoo the best and expressing her love for her. Jisoo then left a comment on her post, calling her "My 1-per-100," which referred to the Korean title of "May I Help You?" and telling her to find strength.
