Pastor of Redeemer Presbyterian Church in New York City and author Timothy Keller is sharing a cancer update and asking people to pray. 

In his update, Keller shares that even though his pancreatic cancer was previously doing well, they recently found new tumours. 

"I will shortly be returning to the National Cancer Institute in Bethesda, MD in order to spend April doing a variation of the immunotherapy that I received last June," says Keller on Facebook. "It was successful in eradicating 99% of the tumors. However, new tumors have developed."

Keller was initially diagnosed with stage four pancreatic cancer in May 2020. Since that time he's continued to write and preach. 

"They are unfortunately in some fairly inconvenient places, so the doctors encouraged us to go through the treatment again, this time targeting a different genetic marker of the cancer."

In previous interviews about his cancer journey this second time around, Keller shared that it's made his prayer life that much stronger, which he's thankful for. 

"It was fairly brutal last June, so we approach this with an awareness of how much prayer we need. Please pray for our trust and dependence on God, for his providential oversight of the medical preparations now in process, and for our desire to glorify God in whatever comes our way. Thank You."
