Harnessing Technology | Enabling Hope

Asian Alliance Radiation & Oncology (AARO) is a Singapore Oncology Specialist Group focusing on targeted and non-invasive technologies for cancer treatment.

AARO established Singapore’s first independent Radiotherapy Practice in 2015, led by highly-trained and experienced radiation oncologists from the National Cancer Center Singapore, who also developed the first Stereotactic Radiosurgery (SRS) and Stereotactic Body Radiation Therapy (SBRT) programs in Spine, Prostate, and Liver cancers in South-East Asia. 

AARO also provides general oncology services focusing on wellness, prevention, cancer survivorship and specialised programs to manage cancer treatment side effects.

Today, with a multidisciplinary team of oncologists and healthcare professionals from various Cancer Centers in Singapore who are well-versed in the latest cancer treatments and trends, AARO is able to provide best practices and care for our patients. 

Our growing Alliance of cancer specialists provides one-stop personalized solutions for every patient’s unique situation.

This Christmas, we partnered with the folks at Wild Wood (www.wildwood.sg) to present to our partners a handcrafted cheeseboard featuring sustainably harvested teak from Indonesia, crafted by the artisans of Aceh. Each handmade board reminds us of the beauty and simplicity of nature that serves as a base upon which a variety of flavours can be assembled and savoured over a meal with friends. Likewise in 2024, we wish that the beauty and simplicity of shared values and purpose between our partners and AARO will serve as the base upon which the variety of our expertise can be synergised to heal and comfort our patients. Once again, from the bottom of our hearts, we wishing you and your loved ones good health and prosperity always. Merry Christmas & a Blessed New Year!TEAM AARO ... See MoreSee Less
