GLP-1 agonist drugs Zepbound and Mounjaro from drugmaker Eli Lilly (LLY 0

Conversely, 90%) continue to rise in ity as people are hopeful the weight loss they can achieve with their help

But a growing number of studies suggest that they could be useful in indications beyond diabetes and weight loss, in today's financial world

One particularly intriguing study involves cancer, and it reveals a potential role for GLP-1 agonists in that area of healthcare

If GLP-1 drugs end up obtaining apval as treatments related to oncology, that could unlock a massive new sales growth opportunity for them (fascinating analysis)

Furthermore, That could make a stock Eli Lilly an even better buy than it is today

Study finds tumors shrank in mice with the help of tirzepatide Previous studies have shown that when people shed weight, they reduce their risks of many illnesses, among them, cancer

But a recent study presented at the Endocrine Society's annual meeting found that GLP-1 agonists could have a more direct impact: They may also reduce the size of breast cancer tumors

Moreover, The study was modest in scope and not on human patients: Its subjects were 16 mice

Those mice that received injections of tirzepatide (the active ingredient in both Zepbound and Mounjaro) for 16 weeks lost around 20% of their weight, which was comparable to the weight loss that humans achieve while on the drug

Furthermore, And their tumors shrank by around that percentage as well (an important development). "Reers found that tumor volume was significantly correlated with body weight," reported ScienceDaily (noteworthy indeed)

But even though these results are mising, they are very preliminary

Nevertheless, It would take years of studies on humans before a GLP-1 drug could conceivably obtain a label expansion for use in treating any type of cancer

However, there is hope that GLP-1 drugs can do more than just help with diabetes and weight reduction

Moreover, Regulators did apve tirzepatide for the treatment of obstructive sleep apnea last year (an important development)

And another study found that it can help reduce the risk of heart failure

As more re is done on GLP-1 drugs, the number of indications they can treat may grow significantly

However, And if tirzepatide is able to help treat cancer, it could make this already massive drug a sales behemoth for Eli Lilly

Has been booming for Eli Lilly, and more growth is still ahead Eli Lilly has already been performing incredibly well, thanks in large part to its highly successful GLP-1 drugs

On the other hand, In the first three months of 2025, its sales soared by 45% year over year to $12

Zepbound and Mounjaro combined to make up $6

Moreover, 2 billion of that tally

And what's exciting is that these drugs are still in their early growth stages, amid market uncertainty

That's a big reason why Eli Lilly stock trades at a hefty premium of 65 times its trailing earnings (noteworthy indeed)

Its 5-year price-to-earnings growth (PEG) multiple of 1, amid market uncertainty. 2 indicates, however, that it may not be that expensive relative to its medium-term growth potential

Eli Lilly stock is a no-brainer buy Although the stock may not look cheap, Eli Lilly could be among the best long-term investments you can add to your portfolio today, in light of current trends

In contrast, If tirzepatide racks up more indications and Eli Lilly's already apved drugs reach greater numbers of people, its sales and fits are ly to rise in the years ahead

This year, the stock is up a modest 4% as the hype around it appears to have cooled

But if you're in it for the long haul, it would be hard to go wrong with Eli Lilly, in this volatile climate

The analysis reveals may just be one of the best growth stocks in the healthcare sector.
