A neurological exam is also usually performed to test a patient\u2019s nerves and brain function.<\/p>\n<p class=\"p1\">Glioma treatment usually begins with surgery, the Mayo Clinic stated. Surgery, however, isn\u2019t always an option.<\/p>\n<p class=\"p1\">If the glioma grows into important parts of the brain, it might be too risky for doctors to remove all of the glioma. Radiation therapy and chemotherapy may be recommended as an alternative for treatment.<\/p>\n<h2 class=\"p1\"><b>What Is the Outlook for Patients With Glioma?<\/b><\/h2>\n<figure id=\"attachment_4063007\" style=\"width: 900px;\" class=\"wp-caption alignnone\">\n<div class=\"ratio-based-placeholder\" style=\"padding-bottom:100%;\"><img loading=\"lazy\" decoding=\"async\" class=\"size-large wp-image-4063007\" src=\"https:\/\/www.usmagazine.com\/wp-content\/uploads\/2025\/08\/kelley-mack-death3.jpg?w=1000&amp;quality=86&amp;strip=all\" alt=\"What Is Glioma Everything to Know About The Walking Dead Star Kelley Mack s Rare Illness\" width=\"1000\" height=\"1000\" srcset=\"https:\/\/www.usmagazine.com\/wp-content\/uploads\/2025\/08\/kelley-mack-death3.jpg?w=100&amp;quality=86&amp;strip=all 100w, https:\/\/www.usmagazine.com\/wp-content\/uploads\/2025\/08\/kelley-mack-death3.jpg?w=200&amp;quality=55&amp;strip=all 200w, https:\/\/www.usmagazine.com\/wp-content\/uploads\/2025\/08\/kelley-mack-death3.jpg?w=300&amp;quality=70&amp;strip=all 300w, https:\/\/www.usmagazine.com\/wp-content\/uploads\/2025\/08\/kelley-mack-death3.jpg?w=400&amp;quality=55&amp;strip=all 400w, https:\/\/www.usmagazine.com\/wp-content\/uploads\/2025\/08\/kelley-mack-death3.jpg?w=500&amp;quality=86&amp;strip=all 500w, https:\/\/www.usmagazine.com\/wp-content\/uploads\/2025\/08\/kelley-mack-death3.jpg?w=600&amp;quality=40&amp;strip=all 600w, https:\/\/www.usmagazine.com\/wp-content\/uploads\/2025\/08\/kelley-mack-death3.jpg?w=700&amp;quality=55&amp;strip=all 700w, https:\/\/www.usmagazine.com\/wp-content\/uploads\/2025\/08\/kelley-mack-death3.jpg?w=800&amp;quality=70&amp;strip=all 800w, https:\/\/www.usmagazine.com\/wp-content\/uploads\/2025\/08\/kelley-mack-death3.jpg?w=900&amp;quality=86&amp;strip=all 900w, https:\/\/www.usmagazine.com\/wp-content\/uploads\/2025\/08\/kelley-mack-death3.jpg?w=1000&amp;quality=86&amp;strip=all 1000w, https:\/\/www.usmagazine.com\/wp-content\/uploads\/2025\/08\/kelley-mack-death3.jpg?w=1200&amp;quality=86&amp;strip=all 1200w\" sizes=\"auto, (max-width: 680px) calc(100vw - 6em), (max-width: 1000px) 80vw, 1000px\"\/><\/div><figcaption class=\"wp-caption-text\"><span class=\"caption\"><br \/>\n Kelley Mack<\/span> <span class=\"credit\">Courtesy of Kelley Mack \/ Instagram<\/span><\/figcaption><\/figure>\n<p class=\"p1\">According to the <span class=\"s1\">Cleveland Clinic<\/span>, survival rates for gliomas vary by tumor type, tumor grade and a person\u2019s age.<\/p>\n<div id=\"news-block\">\n<div class=\"newsletter-form  \">\n<div class=\"newsletter-signup__success\" aria-live=\"polite\">\n<h3>Thank You!<\/h3>\n<p>You have successfully subscribed.<\/p>\n<\/p><\/div>\n<\/div><\/div>\n<p class=\"p1\">The older someone is when they\u2019re diagnosed and treated, the worse the outlook.<\/p>\n<div class=\"link-related article link-related__with-thumb\">\n\t\t\t<a rel=\"nofollow\" target=\"_blank\" class=\"article__thumbnail related-ab-test\" href=\"https:\/\/www.usmagazine.com\/celebrity-news\/news\/who-was-kelley-macks-boyfriend-logan-lanier-supportive-partner-revealed\/\" target=\"\" data-source=\"01\"><\/p>\n<figure class=\"article__figure\">\n<div style=\"padding-bottom:56.25%;\" class=\"ratio-based-placeholder\"><img loading=\"lazy\" decoding=\"async\" src=\"\/wp-content\/uploads\/2025\/08\/Logan-Lanier-Kelley-Mack.jpg?crop=129px%2C481px%2C762px%2C432px&amp;resize=400%2C225&amp;quality=40&amp;strip=all\" srcset=\"\" sizes=\"auto, (max-width: 480px) 400px, (max-width: 770px) calc(100vw - 6em), 200px\" alt=\"Logan-Lanier-Kelley-Mack\" width=\"400\" height=\"225\" data-fallback-img=\"\/wp-content\/uploads\/2025\/08\/Logan-Lanier-Kelley-Mack.jpg?quality=40&amp;strip=all\"\/><\/div>\n<\/figure>\n<p>\t\t<\/a><\/p>\n<div class=\"article__content\">\n<h3 class=\"article__title\">\n\t\t\t<a rel=\"nofollow\" target=\"_blank\" class=\"article__title-link related-ab-test\" href=\"https:\/\/www.usmagazine.com\/celebrity-news\/news\/who-was-kelley-macks-boyfriend-logan-lanier-supportive-partner-revealed\/\" target=\"\" data-source=\"01\"><br \/>\n    <span class=\"related-badge\">Related: <\/span><span class=\"related-title\">Who Was Kelley Mack&#8217;s Boyfriend?
