A promising type of cancer care that’s largely been available only in Boston is coming to central Massachusetts.

The state Public Health Council on Wednesday unanimously approved UMass Memorial Health Care’s application to buy a proton beam, and expand UMass Memorial’s Cancer Center at Marlborough Hospital in order to offer proton therapy services.

The project is expected to cost nearly $54 million.

UMass Memorial says the investment will boost regional health care access, improve clinical outcomes and quality of life for patients, potentially increase survival rates, and reduce travel burdens for patients who currently must trek to Boston to receive proton therapy over 24 consecutive sessions.

SpaceX planning IPO

SpaceX is moving ahead with plans for an initial public offering that would seek to raise significantly more than $30 billion, people familiar with the matter said, in a transaction that would make it the biggest listing of all time.

The Elon Musk-led company is targeting a valuation of about $1.5 trillion for the entire company, which would leave SpaceX near the market value that Saudi Aramco established during its record 2019 listing. The oil major raised $29 billion at the time.

SpaceX’s management and advisers are pursuing a listing as soon as mid-to-late 2026, said some of the people, who declined to be identified because the matter is confidential. The timing of the IPO could change based on market conditions and other factors, and one of the people said it could slip into 2027.

A representative for SpaceX didn’t immediately respond to a request for comment.
