My heart goes out to you and your family for having to confront your brother’s illness and to make these heart-wrenching decisions. I pray for your brother’s refuah (recovery).
Without knowing you or your brother personally, it is difficult to offer a definitive answer to your question. What I can do is lay out some general principles and values to help you make a decision. It is important to keep in mind that in difficult situations like this, there is no absolute right or wrong decision. You have to do what makes the most sense for you and your brother, recognizing that the situation may change at any moment.
In general, Judaism does not place values of one mitzvah over another. The normative principle is mitzvah ha-ba’ah le-yadcha al tachlitzenah (If the opportunity to perform a mitzvah comes to you, do not push it off). That is to say, do the mitzvah which can be performed at this moment without worrying about future mitzvoth that or may not arise.
While Judaism demands that we seek the proper medical treatment and take the advice offered by experts seriously, it also demands of us that we retain our faith in God and in God’s ability to perform miracles. We often pray to God as the Rofeh cholim (He Who heals the ill) and even when the medical prognosis says otherwise, we continue to pray and beseech God to “prove the experts wrong” and heal your brother.
Another question to consider is your brother’s current condition. If he is cognizant and aware of his surroundings, the effect of a visit from a loved one can do wonders for his own peace of mind and in helping him in his fight against cancer. It may also be helpful for you to be able to visit with your brother and talk with him face to face.
From these perspectives, it would seem to me most important to visit your brother now.
However, an argument can be made for “waiting.” There are some people who do not want their last interaction with a loved one to be in a hospital while the person is in a debilitated state. If your brother is not cognizant of his surroundings then the impact of a visit may not be as strong (though there is lots of research that shows that even patients who are unconscious respond to the well-wishes and prayers of their loved ones). Finally, it is worthwhile to consider the laws of death and mourning. Halachah (Jewish law) focuses us in two different ways. On the one hand we have a responsibility to show kavod ha-met – honor and dignity to the dead. Ways in which we show kavod ha-met include ensuring a proper and timely burial, and eulogizing the deceased. At the same time there is an obligation of nichum aveilim (comforting the mourners). This is the primary focus of the week of Shivah in which the community provides for the bereaved by allowing them to reflect on their loss and by providing for their physical needs. It is therefore a legitimate question to ask yourself what will be most helpful and meaningful to you should your brother pass away, God forbid. Some people are most comforted by being at the funeral and observing shivah in the community of the deceased with the rest of the family. Others are most comforted by being in their home community and reflecting on their loss with their friends and loved ones.
As I wrote at the beginning, without knowing you or your family personally, it is impossible to offer a definitive answer to your difficult question. I hope that the values and principles outlined above are helpful in making a decision. Most of all, I hope and pray that your brother defies the odds and recovers from his illness.
