The flamboyant left-hander has said that only four days are left for his chemotherapy.
“My last stretch 4 mor dys to go Can’t wait fr it to end Set me free dear lord,” Yuvraj tweeted.
Yuvraj had last month stated that the tumour between his lungs is almost out of his system.
Yuvraj, who has been in Boston since last month, is expected to be back on the field in the first week of May, according to his doctor.
The 30-year-old has gone bald during the treatment, which will go on till the last week of March before the process of rehabilitation starts in April.
After being diagnosed with the illness, Yuvraj has not played competitive cricket since taking part in two of three home Tests against the West Indies in November.
He has so far scored 8,051 runs in 274 one-dayers and 1,775 runs in 37 Tests since making his international debut in 2000.
He was named Player of the Tournament in the World Cup for scoring 362 runs and grabbing 15 wickets in nine matches.
During the treatment, Yuvraj had been paid a visit by legendary former Indian spinner Anil Kumble.
